CVE-2026-31997

OpenClaw < 2026.3.1 - Executable Rebind via Unbound PATH-token in system.run Approvals

State: Published
Severity: 4.4 Medium
Published: Mar 19, 2026
Updated: Jun 23, 2026
Reserved: Mar 10, 2026

Description

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.
