Creator: Rapid7

Keywords: CVE, CVE-2026-2297, CWE-668, CVSS 5.7, EPSS 0.00212

The import hook in CPython that handles legacy *.pyc files (SourcelessFileLoader) is incorrectly handled in FileLoader (a base class) and so does not use io.open_code() to read the .pyc files. sys.audit handlers for this audit event therefore do not fire.
