CVE-2026-41392: OpenClaw: Shell init-file options could satisfy exec allowlist script matching

Summary

Before OpenClaw 2026.3.31, exec allowlist matching could treat shell init-file wrapper invocations as if the approved script itself were being executed. Shell options such as --rcfile, --init-file, and --startup-file could therefore inherit allowlist trust from a matched script path even though the shell loaded attacker-chosen initialization first.

Impact

This issue only applied when exec allowlist or allow-always behavior was enabled and the attacker could steer a shell-wrapper command shape that used init-file options. The result was a narrower allowlist bypass, not generic arbitrary command execution from an untrusted boundary.
