Upgrade open-webui to version 0.11.1 or higher.
Overview
open-webui is an Open WebUI
Affected versions of this package are vulnerable to Server-side Request Forgery (SSRF) in the SafePlaywrightURLLoader process when the Playwright web loader engine is enabled. An attacker can access internal network resources and sensitive data by submitting a crafted URL and controlling the authoritative DNS for the hostname, causing the browser to resolve the address to an internal service during a second lookup. This is only exploitable if the WEB_LOADER_ENGINE is set to 'playwright', a reachable Playwright browser is available, and the attacker controls the authoritative DNS for the submitted hostname.
