This link is maintained to preserve external references.\n\n## Original Description\nOpenClaw before 2026.5.26 contains a hostname validation vulnerability allowing attackers to bypass blocklist comparisons using trailing-dot notation in model or workspace-derived URLs. Attackers can exploit inconsistent hostname checks to reach destinations that operators intended to block through hostname policies.\n\n## Affected packages\n\n- `openclaw <= 2026.5.22`\n\n## Remediation\n\nRefer to the advisory for the patched release.","depth":"sunlit","depthScore":36,"depthScoreParts":{"impact":35.8,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
