CVE-2026-41390
OpenClaw < 2026.3.28 - Exec Allowlist Bypass via Unregistered /usr/bin/script Wrapper
OpenClaw before 2026.3.28 contains an exec allowlist bypass vulnerability where allow-always persistence fails to unwrap /usr/bin/script and similar wrappers before storing trust decisions. Attackers can obtain user approval for one wrapped command to persist trust for wrapper binaries that execute different underlying programs.

OpenClaw has a gateway exec allowlist allow-always bypass via unregistered /usr/bin/script wrapper
Summary
Allow-always persistence did not unwrap /usr/bin/script and similar wrappers to the actual executed target before storing trust decisions.
Impact
A user approval for one wrapped command could persist trust for a wrapper binary that later executed a different underlying program.
