Summary
SnapOtter from 1.15.10 through 2.2.0 has a missing authorization flaw (CWE-862) in its upload and preview API handlers, which skip permission checks.

Description from the CNA
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.
