What is CVE-2026-53836?

OpenClaw, prior to version 2026.5.12, features a vulnerability that permits remote authenticated users to bypass execution allowlist checks. This is achieved through the use of abbreviated flag aliases in PowerShell encoded commands, which are not recognized by the allowlist parser, allowing attackers to execute arbitrary PowerShell content. This vulnerability raises significant security concerns as it may facilitate unauthorized access and command execution within affected systems.
