CVE-2026-33470 — Frigate has cross-camera snapshot disclosure via unrestricted timeline IDs and missing authorization in /api/events/{event_id}/snapshot-clean.webp

Frigate is a network video recorder (NVR) with realtime local object detection for IP cameras. In version 0.17.0, a low-privilege authenticated user restricted to one camera can access snapshots from other cameras. This is possible through a chain of two authorization problems: `/api/timeline` returns timeline entries for cameras outside the caller's allowed camera set, then `/api/events/{event_id}/snapshot-clean.webp` declares `Depends(require_camera_access)` but never actually validates `event.camera` after looking up the event. Together, this allows a restricted user to enumerate event IDs from unauthorized cameras and then fetch clean snapshots for those events. Version 0.17.1 fixes the issue.

Low

Who exploits it and how urgent it is

A 0–100 score combining confirmed exploitation, ransomware and APT use, public exploits, EPSS and severity.

No exploitation signal in the sources consulted so far.

How the score was calculated

EPSS 0.3% (30-day exploitation probability)+4
Technical severity (medium)+3
CISA SSVC: exploitation "poc"+5

The score orders the patch queue; it does not replace your asset context (internet exposure, criticality, compensating controls).

Triage

Is it exploited, how likely is exploitation, what does it touch, and how severe do the sources call it.

First 24 hours

Ordered from the record’s own fields — exposure first, because you cannot patch what you have not found. A rule-generated starting point.

Identify exposed assets running the affected vendor/product/version combinations (Blakeblackshear Frigate, Frigate Frigate).
Apply the documented mitigations until a definitive fix is available.
Search available logs for exploit probes matching the vulnerability class (access control), errors and authentication anomalies.

What should defenders know first?

CVE-2026-33470 is "Frigate has cross-camera snapshot disclosure via unrestricted timeline IDs and missing authorization in /api/events/{event_id}/snapshot-clean.webp", rated Medium. It affects Frigate (Blakeblackshear); versions are in the scope table. It is not in CISA KEV, which does not rule out exploitation. CVSS 4.3 describes technical severity. EPSS 0.33% estimates the probability of exploitation in 30 days; neither replaces your asset context. First verify whether exposed or business-critical assets run the affected versions, apply vendor fixes or mitigations, and preserve logs for review.
