Summary
BBOT: Symlink-Following Arbitrary Write via github_workflows Module
Details

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.

Severity
2.2 (Low)
CVSS:3.1/AV:L/AC:H/PR:L/UI:R/S:U/C:N/I:L/A:N
