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.
Does this matter?
Lower severity and a low EPSS score (0.22%). Track it; it rarely justifies an emergency change on its own.
Description
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.
