immich is a high performance self-hosted photo and video management solution. Prior to version 2.5.0, API keys can escalate their own permissions by calling the update endpoint, allowing a low-privilege API key to grant itself full administrative access to the system. Version 2.5.0 fixes the issue.
immich before 3.0.3 contains a broken access control vulnerability in the PUT /albums/:id/user/:userId endpoint that allows shared album editors to modify member roles without owner-only restrictions. Attackers with editor access can demote the album owner to editor and promote themselves to owner in sequential requests, gaining full control including deletion and eviction capabilities.
