Hermes WebUI before version 0.51.269 contains a profile isolation bypass vulnerability that allows authenticated users to access data belonging to other profiles by querying the session search endpoint without active-profile filtering. Attackers can send requests to the sessions search handler to retrieve session titles and transcript message content from profiles other than their own active profile.
