How to Fix CVE-2024-32874
To remediate this vulnerability, upgrade all affected Frigate dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.
frigate
fixed: 0.13.2
pip install frigate>=0.13.2
Verify Direct and Transitive Dependencies
Run the following command in your project directory to verify that all resolved dependencies use the patched release:
pip show frigateHow to Check if You Are Affected
To determine whether your Python environment is affected by CVE-2024-32874, inspect your installed packages using pip:
pip show frigateAnalyze the terminal output to locate any version of Frigate in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.13.2), your application is affected.
Note: The pip show frigate command checks currently installed packages in your active Python environment.
Technical Details
Vulnerability Mechanism & Technical Analysis
This vulnerability is classified under CWE-770: Allocation of Resources Without Limits or Throttling, where the product allocates a reusable resource or group of resources on behalf of an actor without imposing any intended restrictions on the size or number of resources that can be allocated. In Frigate, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.
Source Advisory Statement
**Important: Exploiting this vulnerability requires the attacker to have access to your Frigate instance, which means they could also just delete all of your recordings or perform any other action. If you have configured authentication in front of Frigate via a reverse proxy, then this vulnerability is not exploitable without first getting around your authentication method. For many obvious reasons in addition to this one, please don't expose your Frigate instance publicly without any kind of authentication.**
## Summary
When uploading a file or retrieving the filename, a user may intentionally use a large Unicode filename which would lead to a application-level denial of service. This is due to no limitation set on the length of the filename and the costy use of the Unicode normalization with the form NFKD under the hood of `secure_filename()`.
I idenfied multiple vulnerable paths on [blakeblackshear/frigate](https://www.github.com/blakeblackshear/frigate/) repository. In all of those paths, it was possible for a malicious user to send a filename equals to the output of : `python3 -c "print('℀' * 1_000_000)"` which would reach the werkzeug `secure_filename()` call , which in turn under the hood uses a compatibility Unicode normalization with NFKC/NFKD form. In sum, the latter call would be costly in matter of CPU resource and may lead to the application-level denial of service.

## Impact
* Application-level Denial of Service, the web app would hung undefinetly and not process any further request due to the use of the malicious payload.
## Mitigation
* Limiting the length of the incoming filename, similar to this commit [fix](https://github.com/django/django/commit/048a9ebb6ea468426cb4e57c71572cbbd975517f).

If you have configured authentication in front of Frigate via a reverse proxy, then this vulnerability is not exploitable without first getting around your authentication method. For many obvious reasons in addition to this one, please don't expose your Frigate instance publicly without any kind of authentication.**\n\n## Summary\n\nWhen uploading a file or retrieving the filename, a user may intentionally use a large Unicode filename which would lead to a application-level denial of service. This is due to no limitation set on the length of the filename and the costy use of the Unicode normalization with the form NFKD under the hood of `secure_filename()`.\n\nI idenfied multiple vulnerable paths on [blakeblackshear/frigate](https://www.github.com/blakeblackshear/frigate/) repository. In all of those paths, it was possible for a malicious user to send a filename equals to the output of : `python3 -c \"print('℀' * 1_000_000)\"` which would reach the werkzeug `secure_filename()` call , which in turn under the hood uses a compatibility Unicode normalization with NFKC/NFKD form. In sum, the latter call would be costly in matter of CPU resource and may lead to the application-level denial of service. \n\n## Vulnerable Paths\n\n<details>\n<summary>Path with 2 steps</summary>\n\n1.
