CVE-2026-120202
Highflame ramparts 0.8.1 through 0.8.10 contains a security scan bypass vulnerability that allows attackers to hide malicious payloads because collectbundlesiblings and walkbundlesubdir skip nested directories and .pyc files. Attackers can distribute a skill bundle with an unchecked-hash .pyc under scripts/ /pycache/ that ramparts silently ignores, while CPython executes it when the skill runs.
