How to Fix GHSA-w2pj-9cgh-mq2c

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

opencv-contrib-python-headless fixed: 4.8.1.78 
pip install opencv-contrib-python-headless>=4.8.1.78
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 opencv-contrib-python-headless

How to Check if You Are Affected

To determine whether your Python environment is affected by GHSA-w2pj-9cgh-mq2c, inspect your installed packages using pip:

pip show opencv-contrib-python-headless

Analyze the terminal output to locate any version of Opencv contrib python headless in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 4.8.1.78), your application is affected.

Note: The pip show opencv-contrib-python-headless command checks currently installed packages in your active Python environment.

Technical Details
