OpenClaw versions prior to 2026.2.23 contain an exec approval bypass vulnerability in allowlist mode where allow-always grants could be circumvented through unrecognized multiplexer shell wrappers like busybox and toybox sh -c commands. Attackers can exploit this by invoking arbitrary payloads under the same multiplexer wrapper to satisfy stored allowlist rules, bypassing intended execution restrictions.
