  "details": "### Summary\n\nOn POSIX nodes, OpenClaw\u0027s `system.run` safe-bin checks could approve a command before shell expansion changed how the command was interpreted. A value that appeared to be a safe-bin argument could expand into additional shell words and become a file operand.\n\nThis issue is limited to paired POSIX node execution through `system.run` with safe-bin or allowlist-style auto-approval. It is not an unauthenticated node takeover.\n\n### Affected configurations\n\nThis affects deployments where:\n\n- a POSIX node is paired to the gateway\n- `system.run` is reachable by an authenticated operator or agent flow\n- exec policy uses safe-bin or allowlist-based auto-approval\n- the approved command contains shell-expanded values that can change argv shape\n\n### Impact\n\nA lower-privilege operator flow could cause an approved safe-bin command to read a node-local file that was not intended by the policy. Depending on the local files available to the node process, this could expose OpenClaw configuration data or other node-local information.\n\nThe issue is a policy-enforcement gap in argv validation, not a general statement that every safe-bin command is unsafe.\n\n### Patched Versions\n\nThe first stable patched version is `2026.5.18`.\n\n### Mitigations\n\nUpgrade to `openclaw@2026.5.18` or later. Before upgrading, avoid broad safe-bin auto-approval for commands that can read arbitrary paths, and prefer explicit approval for node commands that touch local files.",
