CVE-2026-77439 Details
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.
A broken access control vulnerability has been identified in Immich, a self-hosted photo and video management solution, prior to version 3.0.3. This vulnerability allows an authenticated user with editor access to a shared album to escalate their privileges by changing the role of the album owner.
