open-webui v0.6.33 is vulnerable to Incorrect Access Control.
MEDIUM 4.3EPSS 0.28%
Does this matter?
Lower severity and a low EPSS score (0.28%). Track it; it rarely justifies an emergency change on its own.
Description
open-webui v0.6.33 is vulnerable to Incorrect Access Control. The API /api/tasks/stop/ directly accesses and cancels tasks without verifying user ownership, enabling attackers (a normal user) to stop arbitrary LLM response tasks.
