CVE-2026-120202 PUBLISHED

Highflame ramparts 0.8.1 through 0.8.10 Skill Bundle Scan Bypass via Nested .pyc

Assigner: VulnCheck
Reserved: 31.10.2026 Published: 31.10.2026 Updated: 31.10.2026

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