XSS via `.py` file containing script tag interpreted as HTML ## Summary A vulnerability exists in the file preview/browsing feature of the application, where files with a `.py` extension that contain JavaScript code wrapped in `<script>` tags may be interpreted and executed as HTML in certain modes. This leads to a stored XSS vulnerability. ## Affected Versions * <= 4.0.0-rc.3 ## PoC Create a `.py` file with arbitrary JavaScript content wrapped in `<script>` tags. For example: ```javascript <script>alert(document.cookie);</script> ``` When a victim views the file in browsing mode (e.g., a rendered preview), the JavaScript is executed in the browser context. --- ## Attack vector An attacker can place such a `.py` file in the system via remote channels, such as: * Convincing a webmaster to download or upload the file; * Tricking users into accessing a file link via public URLs. ## Required permissions * None, if public or visitor access is enabled. * If the file is uploade...

### Impact Session tokens remain valid on the server after user logout, creating a security gap where: - Compromised tokens (via XSS, network interception, or device theft) continue to work even after the user logs out - The sessions stored in the database still expire, limiting the duration during which this could be exploited - Users cannot fully invalidate their sessions when logging out from shared or potentially compromised devices - by default, changing one's password *does* invalidate all other sessions, so changing your password as a security measure would have been effective - May cause compliance issues with security frameworks requiring complete session ### Patches Upgrade to version 2.10.0. After upgrading, users must update their AuthController implementation to use the new `clear_session/2` function with their OTP app name. You will be prompted to do so with a compile-time error. If you do not have the setting `require_token_presence_for_authentication?` set to `...

Mezzanine CMS, in versions prior to 6.1.1, contains a Stored Cross-Site Scripting (XSS) vulnerability in the admin interface. The vulnerability exists in the "displayable_links_js" function, which fails to properly sanitize blog post titles before including them in JSON responses served via "/admin/displayable_links.js". An authenticated admin user can create a blog post with a malicious JavaScript payload in the title field, then trick another admin user into clicking a direct link to the "/admin/displayable_links.js" endpoint, causing the malicious script to execute in their browser.

### Impact When a user without script right creates a document with an `XWiki.Notifications.Code.NotificationDisplayerClass` object, and later an admin edits and saves that document, the possibly malicious content of that object is output as raw HTML, allowing XSS attacks. While the notification displayer executes Velocity, the existing generic analyzer already warns admins before editing Velocity code. Note that warnings before editing documents with dangerous properties have only been introduced in XWiki 15.9, before that version, this was a known issue and the advice was simply to be careful. ### Patches This vulnerability has been patched in XWiki 15.10.16, 16.4.7, and 16.10.2 by adding a required rights analyzer that warns the admin before editing about the possibly malicious code. ### Workarounds We're not aware of any real workarounds apart from just being careful with editing documents previously edited by untrusted users as a user with script, admin or programming right.

### Impact This security advisory is a part of IBEXA-SA-2025-003, which resolves XSS vulnerabilities in several parts of the back office of Ibexa DXP. Back office access and varying levels of editing and management permissions are required to exploit these vulnerabilities. This typically means Editor or Administrator role, or similar. Injected XSS is persistent and can be reflected in the front office, possibly affecting end users. The fixes ensure XSS is escaped, and any existing injected XSS is rendered harmless. ### Patches - See "Patched versions". - https://github.com/ibexa/fieldtype-richtext/commit/4a4a170c7faa4807ae0f74c581481b835bab3caf ### Workarounds None.
