Detailsinfo

A vulnerability, which was classified as critical, was found in OpenClaw (the affected version is unknown). This affects the function validateScriptFileForShellBleed. The manipulation with an unknown input leads to a incomplete blacklist vulnerability. CWE is classifying the issue as CWE-184.

This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

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.
