Description

PhotoPrism before 260601-a7d098548 contains a broken access control vulnerability that allows authenticated non-admin users to modify other users' profile information by sending requests to arbitrary user endpoints. Attackers can exploit the missing session-to-user identifier validation in the PUT users API endpoint to overwrite another user's profile details without authorization.
