Impact
Authenticated attackers with minimal permissions can stage arbitrary files outside storage quotas and feed crafted inputs to media decoders. They need valid credentials, such as a low-privilege settings:read API key.
Root cause
Endpoints for upload, preview, and preview generation fail to verify user permissions before processing requests.
Affected systems
SnapOtter 1.15.10 through 2.2.0
CVSS v3.1 · CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:L
Fix & remediation
Upgrade to a version past 2.2.0 or apply commit 1544966b52b8f2b40ef3794e43ffd4f0214550ba; if you cannot patch immediately, block requests to /api/v1/upload, /api/v1/preview, and /api/v1/preview/generate at your reverse proxy.
AI-suggested. Run it in staging first and check it against the vendor advisory. Why?
NVD 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.
