OpenClaw versions prior to 2026.3.1 fail to pin executable identity for non-path-like argv[0] tokens in system.run appro

OpenClaw versions prior to 2026.3.1 fail to pin executable identity for non-path-like argv[0] tokens in system.run approvals, allowing post-approval executable rebind attacks. Attackers can modify PATH resolution after approval to execute a different binary than the operator approved, enabling arbitrary command execution.
