Vulnerability from pysec - Published: 2026-07-07 14:34 - Updated: 2026-07-23 09:44

Details

A Stored Cross-Site Scripting (XSS) vulnerability exists in the chat file upload functionality of open-webui/open-webui version 0.3.8. An attacker can inject malicious content into a file, which, when accessed by a victim through a URL or shared chat, executes JavaScript in the victim's browser. This can lead to user data theft, session hijacking, malware distribution, and phishing attacks.
