CVE-2026-12567
Symlink-following arbitrary write via github_workflows module
The github_workflows module constructs local directory paths from user-controlled repository names without validating for symlinks. A local attacker sharing the scan directory can plant a symlink at the predictable output path, causing workflow data to be written to an attacker-chosen location.
