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.

This high-severity CVE scores 8.3 under the CNA's CVSS (NVD's own analysis pending). EPSS exploit-prediction score not yet available (the EPSS model rescores nightly; freshly-published CVEs typically appear within 48 hours). GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).
