{"id":"CVE-2026-32043","aliases":["GHSA-mwcg-wfq3-4gjc"],"url":"https://o3.security/vulnerability/CVE-2026-32043","summary":"OpenClaw < 2026.2.25 - Time-of-Check-Time-of-Use via Mutable Symlink in system.run cwd Parameter","details":"### Summary\nIn `openclaw@2026.2.24`, approval-bound `system.run` on node hosts could be influenced by mutable symlink `cwd` targets between approval and execution.\n\n### Details\nApproval matching on the gateway validated command/argv and binding fields, including `cwd`, as provided text. Node execution later used runtime `cwd` resolution. A symlinked `cwd` could therefore be retargeted after approval and before spawn.\n\nOpenClaw's trust model does not treat one shared gateway as a multi-tenant adversarial boundary, but approval integrity is still a security boundary for operator-reviewed command execution.\n\n### Affected Packages / Versions\n- Package: `openclaw` (npm)\n- Affected: `<= 2026.2.24`\n- Patched: `>= 2026.2.25` \n\n### Fix Commit(s)\n- `f789f880c934caa8be25b38832f27f90f37903db`\n\n### Remediation\nThe fix adds defense-in-depth hardening for approval-bound node execution:\n- reject symlink `cwd` paths for approval-bound `system.run`\n- canonicalize path-like executable argv before spawn\n- bind CLI approval requests to exact `commandArgv`\n\n### Release Process Note\nPatched version is pre-set to the release (`2026.2.25`). Advisory published with npm release `2026.2.25`.\n\nOpenClaw thanks @tdjackey for reporting.","published":"2026-03-21T00:42:18.279Z","modified":"2026-08-12T03:51:29.880652538Z","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"openclaw","fixedVersion":"2026.2.25"}],"fix":{"url":"https://github.com/openclaw/openclaw/commit/f789f880c934caa8be25b38832f27f90f37903db","label":"openclaw/openclaw@f789f88"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/32xxx/CVE-2026-32043.json"},{"type":"ADVISORY","url":"https://github.com/openclaw/openclaw/security/advisories/GHSA-mwcg-wfq3-4gjc"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-32043"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/openclaw-time-of-check-time-of-use-via-mutable-symlink-in-system-run-cwd-parameter"},{"type":"FIX","url":"https://github.com/openclaw/openclaw/commit/f789f880c934caa8be25b38832f27f90f37903db"},{"type":"PACKAGE","url":"https://github.com/openclaw/openclaw"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:29.880652538Z"}}
