How to Fix CVE-2023-0488

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

pyload-ng fixed: 0.5.0b3.dev42

pip install pyload-ng>=0.5.0b3.dev42

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 pyload-ng

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2023-0488, inspect your installed packages using pip:

pip show pyload-ng

Analyze the terminal output to locate any version of Pyload ng in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.5.0b3.dev42), your application is affected.

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