Summary

CVE-2026-33470 is a medium-severity Missing Authorization (CWE-862) vulnerability in Frigate Frigate. Its CVSS base score is 6.5 (Medium).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 23th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified map to AC-3 (Access Enforcement) and AC-6 (Least Privilege) — see the control section below for these in your framework.

Vulnerability Data

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…

more

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.

MITRE ATT&CK Enterprise TechniquesAI

T1190 Exploit Public-Facing Application Initial Access
Adversaries may attempt to exploit a weakness in an Internet-facing host or system to initially access a network.
Why these techniques?

Authorization bypass in exposed Frigate web API directly enables exploitation of a public-facing application to access restricted camera data.

Mitigating Controls (NIST 800-53 r5) AI

prevent

Directly enforces authorization checks on API endpoints so that timeline queries and snapshot retrieval are limited to the caller's permitted camera set.

prevent

Implements least-privilege restrictions per camera; the missing validation of event.camera after lookup violates the intended per-user camera scoping.

prevent

Enforces information-flow rules between camera-specific data objects and user sessions, blocking cross-camera snapshot leakage.

PR.AA-05 full match
prevents

Explicitly requires defining, enforcing, and reviewing authorizations and least privilege, directly preventing missing authorization checks.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.

prevents

Requiring authentication and credentials before any access occurs eliminates the absence of authorization checks that would otherwise allow an unauthenticated actor to reach protected resources.

prevents

Requiring formal authorization of every access request before rights are granted ensures that checks for required permissions are performed, preventing missing authorization checks from being introduced.

prevents

Mandatory authorization checks and central records of granted rights ensure that every access attempt is preceded by an explicit decision rather than relying on missing checks.

mitigates

Segregating the approval of access rights from their implementation provides an independent check that reduces the impact of missing authorization checks in the resulting system configuration.

detects

By requiring competent outsiders to verify that every function enforces the need-to-know principle, the control lowers the likelihood that missing authorization checks persist undetected.

prevents

Defining authorization responsibilities and reviewing risk-treatment progress throughout the project lifecycle catches missing authorization checks before the system is deployed.
