OpenClaw - Shell-Bleed Protection Preflight Validation Bypass

Published Apr 2, 2026 · Updated Nov 8, 2026 · Assigned by VulnCheck

Description

OpenClaw versions prior to commit 8aceaf5 contain a preflight validation bypass vulnerability in shell-bleed protection that allows attackers to execute blocked script content by using piped or complex command forms that the parser fails to recognize. Attackers can craft commands such as piped execution, command substitution, or subshell invocation to bypass the validateScriptFileForShellBleed() validation checks and execute arbitrary script content that would otherwise be blocked.
