Vulnerability Title
Immich: Album Editor can escalate to Owner role and remove Owner-role members via unguarded API endpoints
Source: CVE Program / CVE List V5
Vulnerability Description
Immich is a self-hosted photo and video management solution. Prior to 3.0.3, an authenticated user with editor access to a shared album can change the existing owner's role because album member role updates do not protect the owner from modification. By demoting the owner and then promoting themselves, an editor can take ownership of the album, remove the original owner, and delete the album. This vulnerability is fixed in version 3.0.3.
