CVE-2026-2297

Published Mar 4, 2026 CWE-668 EPSS 0.21% (11th pctl)

Overview

CVE-2026-2297 is a known-severity vulnerability. It was published on March 4, 2026.

Technical Description

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.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
