GHSA-35pq-7pv2-2rfw: ps_contactinfo has a potential XSS due to usage of the nofilter tag in template

### Impact This can not be exploited in a fresh install of PrestaShop, only shops made vulnerable by third party modules are concerned. For example, if your shop has a third party module vulnerable to SQL injections, then ps_contactinfo might execute a stored XSS in FO. ### Patches The long term fix is to have all your modules maintained and updated. The fix on ps_contactinfo will keep formatted addresses from displaying an xss stored in the database. ### Workarounds none ### References none

GHSA-qwj6-q94f-8425: MathLive's Lack of Escaping of HTML allows for XSS

### Summary Despite normal text rendering as LaTeX expressions, preventing XSS, the library also provides users with commands which may modify HTML, such as the `\htmlData` command, and the lack of escaping leads to XSS. ### Details Overall in the code, other than in the `test` folder, no functions escaping HTML can be seen. ### PoC 1. Go to https://cortexjs.io/mathlive/demo/ 2. Paste either `\htmlData{><img/onerror=alert(1)"src=}{}` or `\htmlData{x=" ><img/onerror=alert(1) src>}{}` in the LaTeX textarea. ### Impact MathLive users who render untrusted mathematical expressions could encounter malicious input using \htmlData that runs arbitrary JavaScript, or generate invalid HTML.

GHSA-79xx-vf93-p7cx: Cross-Site Scripting (XSS) vulnerability in generateNavigation() function in PhpSpreadsheet

### Summary The researcher discovered zero-day vulnerability Cross-Site Scripting (XSS) vulnerability in the code which translates the XLSX file into a HTML representation and displays it in the response. ### Details When generating the HTML from an xlsx file containing multiple sheets, a navigation menu is created. This menu includes the sheet names, which are not sanitized. As a result, an attacker can exploit this vulnerability to execute JavaScript code. ```php // Construct HTML $html = ''; // Only if there are more than 1 sheets if (count($sheets) > 1) { // Loop all sheets $sheetId = 0; $html .= '<ul class="navigation">' . PHP_EOL; foreach ($sheets as $sheet) { $html .= ' <li class="sheet' . $sheetId . '"><a href="#sheet' . $sheetId . '">' . $sheet->getTitle() . '</a></li>' . PHP_EOL; ++$sheetId; } $html .= '</ul>' . PHP_EOL; } ``` ...

GHSA-w59h-3x3q-3p6j: Authenticated Stored XSS in YesWiki

# Authenticated Stored XSS in YesWiki <= 4.4.5 ### Summary It is possible for an authenticated user with rights to edit/create a page or comment to trigger a stored XSS which will be reflected on any page where the resource is loaded. This Proof of Concept has been performed using the followings: - YesWiki v4.4.5 (`doryphore-dev` branch, latest) - Docker environnment (`docker/docker-compose.yml`) - Docker v27.5.0 - Default installation ### Details The vulnerability makes use of the content edition feature and more specifically of the `{{attach}}` component allowing users to attach files/medias to a page. When a file is attached using the `{{attach}}` component, if the resource contained in the `file` attribute doesn't exist, then the server will generate a file upload button containing the filename. This part of the code is managed in `tools/attach/libs/attach.lib.php` and the faulty function is **[showFileNotExits()](https://github.com/YesWiki/yeswiki/blob/doryphore-dev/tools/att...

GHSA-wphc-5f2j-jhvg: Unauthenticated DOM Based XSS in YesWiki

# Unauthenticated DOM Based XSS in YesWiki <= 4.4.5 ### Summary It is possible for any end-user to craft a DOM based XSS on all of YesWiki's pages which will be triggered when a user clicks on a malicious link. This Proof of Concept has been performed using the followings: - YesWiki v4.4.5 (`doryphore-dev` branch, latest) - Docker environnment (`docker/docker-compose.yml`) - Docker v27.5.0 - Default installation ### Details The vulnerability makes use of the search by tag feature. When a tag doesn't exist, the tag is reflected on the page and isn't properly sanitized on the server side which allows a malicious user to generate a link that will trigger an XSS on the client's side when clicked. This part of the code is managed by `tools/tags/handlers/page/listpages.php`, and **[this piece of code](https://github.com/YesWiki/yeswiki/blob/doryphore-dev/tools/tags/handlers/page/listpages.php#L84)** is responsible for the vulnerability: ```php $output .= '<div class="alert alert-info">...

GHSA-wv8v-rmw2-25wc: XSS/HTML Injection Vulnerability in Umbraco Backoffice Components

GHSA-jhvj-f397-8w6q: HAL Console has a Cross Site Scripting (XSS) vulnerability of user input

A flaw was found in the HAL Console in the Wildfly component, which does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output used as a web page that is served to other users. The attacker must be authenticated as a user that belongs to management groups “SuperUser”, “Admin”, or “Maintainer”. ### Impact Cross-site scripting (XSS) vulnerability in the management console. ### Patches Fixed in [HAL 3.7.7.Final](https://github.com/hal/console/releases/tag/v3.7.7) ### Workarounds No workaround available ### References - https://access.redhat.com/security/cve/CVE-2025-23366 - https://bugzilla.redhat.com/show_bug.cgi?id=2337619

GHSA-g84x-g96g-rcjc: Librenms has a reflected XSS on error alert

XSS on the parameters:`/addhost` -> param: community of Librenms versions 24.10.1 ([https://github.com/librenms/librenms](https://github.com/librenms/librenms)) allows remote attackers to inject malicious scripts. When a user views or interacts with the page displaying the data, the malicious script executes immediately, leading to potential unauthorized actions or data exposure. **Proof of Concept:** 1. Navigate to the /addhost path. 2. Fill in all required fields. 3. In the Community field, enter the following payload: `"><img src=a onerror="alert(1)">`. ![image](https://github.com/user-attachments/assets/025a7692-e730-4e3b-bca7-761ed2a60cf7) 4.
