OpenClaw exec approvals could be bypassed in allowlist mode when allow-always was granted through unrecognized multiplexer shell wrappers (notably busybox sh -c and toybox sh -c).
openclaw (npm)<= 2026.2.22-22026.2.22-2 (checked on February 24, 2026)main: yes2026.2.23Wrapper analysis treated busybox/toybox invocations as non-wrapper commands in this path, so allow-always persisted the wrapper binary path instead of the inner executable. That allowed later arbitrary payloads under the same multiplexer wrapper to satisfy the stored allowlist rule.
The fix hardens wrapper detection and persistence behavior for these multiplexer shell applets so approvals bind to intended inner executables and fail closed when unwrap safety is uncertain.

OpenClaw thanks @jiseoung for reporting.
