Sources and claim methodology

Upstream source description

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.
