**Name of the Vulnerable Software and Affected Versions** CPython (affected versions not specified) **Description** The import hook in CPython that handles legacy *.pyc files using `SourcelessFileLoader` is incorrectly handled within `FileLoader`, a base class. This results in the failure to utilize `io.open code()` when reading these .pyc files. Consequently, `sys.audit` handlers for the associated audit event do not activate as expected. **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability.
