Summary
OpenClaw < 2026.2.23 - Exec Approval Bypass via Unrecognized Multiplexer Shell Wrappers
Original description
The description as published by the source.
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.
