CVE-2026-108165 PUBLISHED

Immich through 3.3.1 contains a missing authorization vulnerability in the partner synchronization stream that allows authenticated partners to read Locked Folder asset metadata because sync queries do not exclude Locked visibility. Attackers with an active partner relationship can call POST /api/sync/stream with PartnerAssetsV2 and PartnerAssetExifsV1 types to obtain GPS coordinates, capture times, descriptions and camera details.
