{"id":"GHSA-fvx6-pj3r-5q4q","summary":"OpenClaw's complex interpreter pipelines could skip exec script preflight validation","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: `\u003c= 2026.4.1`\n- Patched versions: `\u003e= 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.","aliases":["CVE-2026-34425"],"modified":"2026-04-06T23:12:30.610996Z","published":"2026-04-06T22:53:48Z","database_specific":{"github_reviewed":true,"github_reviewed_at":"2026-04-06T22:53:48Z","nvd_published_at":null,"cwe_ids":["CWE-184"],"severity":"MODERATE"},"references":[{"type":"WEB","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":"WEB","url":"https://github.com/openclaw/openclaw/commit/8aceaf5d0f0ec552b75a792f7f0a3bfa5b091513"},{"type":"PACKAGE","url":"https://github.com/openclaw/openclaw"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/openclaw-shell-bleed-protection-preflight-validation-bypass"}],"affected":[{"package":{"name":"openclaw","ecosystem":"npm","purl":"pkg:npm/openclaw"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"2026.4.2"}]}],"database_specific":{"last_known_affected_version_range":"\u003c= 2026.4.1","source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/04/GHSA-fvx6-pj3r-5q4q/GHSA-fvx6-pj3r-5q4q.json"}}],"schema_version":"1.9.0"}
