| Summary | Duplicate Advisory: Hostname checks could treat trailing-dot hosts inconsistently ## Duplicate Advisory This advisory has been withdrawn because it is a duplicate of GHSA-gxg4-2rrr-jhc7. This link is maintained to preserve external references. ## Original Description OpenClaw 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. |
