Descripción técnica

Open WebUI from 0.7.0 before 0.11.4 contains a cross-origin message handling vulnerability in SyncStatsModal that allows any website to steal a signed-in user's session token by posting unvalidated verify:chat messages. Attackers can supply a path-traversal chat id redirecting the authenticated stats export request to the auths endpoint, receiving the victim's JWT for full API access.
