{"id":"CVE-2026-34425","aliases":["GHSA-fvx6-pj3r-5q4q"],"url":"https://o3.security/vulnerability/CVE-2026-34425","summary":"OpenClaw - Shell-Bleed Protection Preflight Validation Bypass","details":"## Summary\n\nBefore OpenClaw 2026.4.2, exec script preflight validation could fail open on complex interpreter invocations such as pipes or other non-simple command forms. In those cases, script-content validation could be skipped entirely.\n\n## Impact\n\nAn attacker-controlled command shape could bypass the intended preflight validation for script execution. This weakened a defense-in-depth guard that was meant to block unsafe script content before execution.\n\n## Affected Packages / Versions\n\n- Package: `openclaw` (npm)\n- Affected versions: `<= 2026.4.1`\n- Patched versions: `>= 2026.4.2`\n- Latest published npm version: `2026.4.1`\n\n## Fix Commit(s)\n\n- `8aceaf5d0f0ec552b75a792f7f0a3bfa5b091513` — close the fail-open bypass in exec script preflight\n\n## Release Process Note\n\nThe fix is present on `main` and is staged for OpenClaw `2026.4.2`. Publish this advisory after the `2026.4.2` npm release is live.\n\nThanks @iskindar for reporting, and thanks @wsparks-vc for coordination.","published":"2026-04-02T18:15:06.544Z","modified":"2026-08-17T03:36:37.627614408Z","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"openclaw","fixedVersion":"2026.4.2"}],"fix":{"url":"https://github.com/openclaw/openclaw/commit/8aceaf5d0f0ec552b75a792f7f0a3bfa5b091513","label":"openclaw/openclaw@8aceaf5"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/34xxx/CVE-2026-34425.json"},{"type":"ADVISORY","url":"https://github.com/openclaw/openclaw/security/advisories/GHSA-fvx6-pj3r-5q4q"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-34425"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/openclaw-shell-bleed-protection-preflight-validation-bypass"},{"type":"FIX","url":"https://github.com/openclaw/openclaw/commit/8aceaf5d0f0ec552b75a792f7f0a3bfa5b091513"},{"type":"PACKAGE","url":"https://github.com/openclaw/openclaw"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-17T03:36:37.627614408Z"}}
