GHSA-Q399-23R3-HFX4

Vulnerability from github – Published: 2026-03-02 22:03 – Updated: 2026-03-19 21:22

Summary

OpenClaw: system.run approvals did not bind PATH-token executable identity, enabling post-approval executable rebind

Details

Summary

For host=node runs, approvals validated command context but did not pin executable identity for non-path-like argv[0] tokens (for example tr). If PATH resolution changed after approval, execution could run a different binary.

Impact

A previously approved action could execute a different executable than the operator approved.

Fix

Node system.run approvals now require immutable systemRunPlan data, and path-token commands are pinned to canonical executable identity (realpath) across approval and execution.

CVE-2026-31997 (GCVE-0-2026-31997)

Vulnerability from cvelistv5 – Published: 2026-03-19 01:00 – Updated: 2026-03-19 14:06 X_Open Source

Title

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

Summary

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.
