CVE-2026-53866 affects OpenClaw versions before 2026.5.12. The vulnerability is an allowlist bypass in shell inline-command parsing. A command request using shell inline-command forms can be routed through a parser case that does not perform the expected allowlist decision, allowing shell content to execute without the intended approval prompt. The issue requires an authenticated operator and is described as remotely exploitable over the network. In practical terms, the flaw causes OpenClaw to mishandle certain inline shell command forms so that command execution policy enforcement is skipped on the vulnerable parser path.
