OpenClaw < 2026.2.22 - Path Traversal via Basename-Only Allowlist Matching on macOS

OpenClaw versions prior to 2026.2.22 on macOS contain a path validation bypass vulnerability in the exec-approval allowlist mode that allows local attackers to execute unauthorized binaries by exploiting basename-only allowlist entries. Attackers can execute same-name local binaries ./echo without approval when security=allowlist and ask=on-miss are configured, bypassing intended path-based policy restrictions.
