Vulnerability Description

Frigate is an open source network video recorder. Prior to version 0.13.0 Beta 3, there is a reflected cross-site scripting vulnerability in any API endpoints reliant on the /<camera_name> base path as values provided for the path are not sanitized. Exploiting this vulnerability requires the attacker to both know very specific information about a user’s Frigate server and requires an authenticated user to be tricked into clicking a specially crafted link to their Frigate instance. This vulnerability could exploited by an attacker under the following circumstances: Frigate publicly exposed to the internet (even with authentication); attacker knows the address of a user’s Frigate instance; attacker crafts a specialized page which links to the user’s Frigate instance; attacker finds a way to get an authenticated user to visit their specialized page and click the button/link. As the reflected values included in the URL are not sanitized or escaped, this permits execution arbitrary Javascript payloads. Version 0.13.0 Beta 3 contains a patch for this issue.

  1. Maintain the observed Atomicorp protections. Keep your Atomicorp commercial rules current and confirm that the selected observed rules (340099 , 340147 , 341099 , 346755 , 347198 ) have not been locally disabled. Atomicorp commercial rules are enabled by default. If you use Atomic WAF, review the applicable policy and rule settings.

  2. Apply the vendor’s remediation. WAF protection is defense in depth and does not replace upgrading or following the affected vendor’s guidance.

    • Affected versions: blakeblackshear frigate version < 0.13.0-beta3.
    • No specific CNA/vendor solution or workaround is included in the current CVE Record . Review the vendor’s security advisories and supported-release guidance before making changes.

  3. Validate after changes. Confirm rule updates are current, review WAF events for the affected application, and test application behavior after vendor upgrades, mitigations, or local policy changes.

Research Notes

Atomicorp WAF protections are designed around attack techniques and exploit behaviors, allowing existing protections to apply across multiple vulnerabilities without requiring a unique rule for every CVE.

Research Note Context

This research note documents exploit-technique analysis associated with this vulnerability and references Atomicorp WAF protections observed during engineering review, testing, or validation activities.

Atomicorp security controls are generally designed to identify and mitigate attack techniques and exploit behaviors rather than individual CVE identifiers. As a result, protections developed for one vulnerability may also apply to related attack variants and future vulnerabilities using similar techniques.
