CVE-2026-109562

SnapOtter 1.15.10 through 2.2.0 contains a missing authorization vulnerability that allows any authenticated principal to call the /api/v1/upload, /api/v1/preview and /api/v1/preview/generate handlers without permission checks. Attackers holding even a settings:read-scoped API key can stage arbitrary files outside storage quota, served unauthenticated via /api/v1/download, and feed crafted input to image and video decoders.
