OpenClaw < 2026.5.12 - Argument Pattern Bypass in Exec Allowlist via Linux and macOS

Assigner: VulnCheck
Reserved: 10.06.2026 Published: 16.06.2026 Updated: 16.06.2026

OpenClaw before 2026.5.12 contains an argument pattern validation bypass in the exec allowlist that allows attackers to execute disallowed arguments for allowlisted executables on Linux and macOS systems. Attackers can bypass configured argPattern restrictions by directly invoking allowlisted executables with unrestricted arguments, potentially enabling unauthorized file access, network access, or command execution.
