{"id":"CVE-2026-43530","aliases":["GHSA-2cq5-mf3v-mx44"],"url":"https://o3.security/vulnerability/CVE-2026-43530","summary":"OpenClaw 2026.2.23 < 2026.4.12 - Weakened Exec Approval Binding via busybox and toybox Applet Execution","details":"## Summary\n\nbusybox and toybox applet execution weakened exec approval binding.\n\n## Affected Packages / Versions\n\n- Package: `openclaw`\n- Ecosystem: npm\n- Affected versions: `>= 2026.2.23 < 2026.4.12`\n- Patched versions: `>= 2026.4.12`\n\n## Impact\n\nOpaque multi-call binaries such as `busybox` and `toybox` could obscure which applet or script-like behavior would actually run, weakening exec approval binding and risk classification.\n\n## Technical Details\n\nThe fix treats `busybox` and `toybox` as opaque mutable script runners and fails closed rather than binding unsafe applet invocations.\n\n## Fix\n\nThe issue was fixed in #65713. The first stable tag containing the fix is `v2026.4.12`, and `openclaw@2026.4.14` includes the fix.\n\n## Fix Commit(s)\n\n- `666f48d9b882a8a1415ca53f9567c72499d850c9`\n- PR: #65713\n\n## Release Process Note\n\nUsers should upgrade to `openclaw` 2026.4.12 or newer. The latest npm release, `2026.4.14`, already includes the fix.\n\n## Credits\n\nThanks to @decsecre583 for reporting this issue.","published":"2026-05-05T11:25:01.066Z","modified":"2026-08-12T03:51:26.888417400Z","cvss":null,"epss":{"score":0.00356,"percentile":0.28502,"asOf":"2026-08-12"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"openclaw","fixedVersion":"2026.4.12"}],"fix":{"url":"https://github.com/openclaw/openclaw/commit/666f48d9b882a8a1415ca53f9567c72499d850c9","label":"openclaw/openclaw@666f48d"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/43xxx/CVE-2026-43530.json"},{"type":"ADVISORY","url":"https://github.com/openclaw/openclaw/security/advisories/GHSA-2cq5-mf3v-mx44"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-43530"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/openclaw-weakened-exec-approval-binding-via-busybox-and-toybox-applet-execution"},{"type":"FIX","url":"https://github.com/openclaw/openclaw/commit/666f48d9b882a8a1415ca53f9567c72499d850c9"},{"type":"WEB","url":"https://github.com/openclaw/openclaw/pull/65713"},{"type":"PACKAGE","url":"https://github.com/openclaw/openclaw"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:26.888417400Z"}}
