In affected releases, a hook-triggered run could select a bundled CLI backend that received owner-scoped MCP loopback authority instead of a scope appropriate for hook ingress.\n\nThis issue affects the boundary between hook-token automation and owner-only MCP tools. It does not affect deployments with hooks disabled.\n\n### Affected configurations\n\nThis affects deployments where hooks are enabled, `/hooks/agent` is reachable with a valid hook token, and a bundled CLI backend can be selected for the hook-triggered run.\n\n### Impact\n\nA caller with the hook token could cause the spawned CLI runtime to see or call MCP tools that should have been owner-only. The practical impact depends on which MCP tools are available; the reported proof used persistent cron state as a representative owner-only action.\n\n### Patched Versions\n\nThe first stable patched version is `2026.5.20`.\n\nFixed in the `2026.5.20` stable release.\n\n### Mitigations\n\nUpgrade to `openclaw@2026.5.20` or later. Keep hook tokens secret, restrict network access to hook endpoints, and disable hooks when they are not needed.\n\n## Affected packages\n\n- `openclaw < 2026.5.20`\n\n## Remediation\n\nUpgrade to a patched release:\n\n- `openclaw 2026.5.20`","depth":"twilight","depthScore":46,"depthScoreParts":{"impact":46.2,"likelihood":0.1,"exploitation":0,"ransomware":0},"changes":[]}
