Overview
open-webui is an Open WebUI
Affected versions of this package are vulnerable to Missing Authorization through the get_event_call process. An attacker can execute arbitrary code and tools in another user's authenticated session by supplying a victim's session_id and leveraging the lack of ownership validation. This enables full session compromise, allowing the attacker to act with the victim's identity and privileges, including potential remote code execution on the server if the victim is an administrator. This is only exploitable if the attacker has a valid user account, the code interpreter is enabled, a shared note exists between attacker and victim, and the victim is online and opens the shared note.
