How to Fix CVE-2025-67492

To remediate this vulnerability, upgrade all affected Weblate dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

Weblate fixed: 5.15 
pip install Weblate>=5.15
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 Weblate

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2025-67492, inspect your installed packages using pip:

pip show Weblate

Analyze the terminal output to locate any version of Weblate in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 5.15), your application is affected.

Note: The pip show Weblate command checks currently installed packages in your active Python environment.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-1286: Improper Validation of Syntactic Correctness of Input, where the product receives input that is expected to be well-formed - i.e., to comply with a certain syntax - but it does not validate or incorrectly validates that the input complies with the syntax. In Weblate, 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

### Impact It was possible to trigger repository updates for many repositories via a crafted webhook payload. ### Patches * https://github.com/WeblateOrg/weblate/pull/17221 ### Workarounds Disabling webhooks completely using ENABLE_HOOKS avoids this vulnerability. ### References Thanks to Hector Ruiz Ruiz & NaxusAI for responsibly disclosing this vulnerability to us.
