CVE-2026-77439
Immich: Album Editor can escalate to Owner role and remove Owner-role members via unguarded API endpoints
What happened?
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.
Affected software and versions

Version information comes from the source record and can include unaffected products and exceptions. Distribution packages may contain backported fixes: an older upstream version alone does not prove a server is affected.
Is it being exploited?
This CVE was not listed in the CISA catalogue at our last retrieval. This does not establish that exploitation is absent.
