OpenClaw before 2026.4.22 contains an exec allowlist analysis vulnerability allowing shell expansion hiding in unquoted heredoc bodies. Attackers can bypass allowlist validation by embedding shell expansion tokens in heredoc bodies to execute unapproved commands at runtime.
AnalysisAI
Shell expansion injection in OpenClaw's exec allowlist validation allows authenticated attackers to bypass command approval controls and execute arbitrary system commands. The vulnerability affects OpenClaw versions prior to 2026.4.22 through improper parsing of unquoted heredoc bodies, where shell expansion tokens ($VAR, $(), etc.) are treated as literal text during allowlist analysis but expanded at runtime. …
