cpython: CPython: Logging Bypass in Legacy .pyc File Handling

A flaw was found in CPython. This vulnerability allows a local user with low privileges to bypass security auditing mechanisms. The issue occurs because the SourcelessFileLoader component, responsible for handling older Python compiled files .pyc, does not properly trigger system audit events. Th...

CVE-2026-2297

CVE-2026-2297 concerns CPython’s import system: the SourcelessFileLoader (legacy .pyc handling) is misimplemented in FileLoader, causing it not to use io.open_code() to read .pyc files. As a result, sys.audit events for this audit point do not fire. The description notes an audit-impacting behavi...
