{"id":"CVE-2026-41407","aliases":["GHSA-jj6q-rrrf-h66h"],"url":"https://o3.security/vulnerability/CVE-2026-41407","summary":"OpenClaw < 2026.4.2 - Timing Side Channel in Shared-Secret Comparison","details":"## Summary\n\nBefore OpenClaw 2026.4.2, several shared-secret comparison call sites still used early length-mismatch checks instead of the shared fixed-length comparison helper. Those paths could leak secret-length information through measurable timing differences.\n\n## Impact\n\nThe affected paths exposed a low-severity timing side channel on secret comparison. The issue did not by itself demonstrate auth bypass, but it weakened the intended constant-time handling for shared secrets.\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- `be10ecef770a4654519869c3641bbb91087c8c7b` — reuse the shared secret comparison helper at affected call sites\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 @kexinoh of Tencent zhuque Lab (https://github.com/Tencent/AI-Infra-Guard) for reporting.","published":"2026-04-28T18:10:04.932Z","modified":"2026-08-12T03:51:33.421828427Z","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/be10ecef770a4654519869c3641bbb91087c8c7b","label":"openclaw/openclaw@be10ece"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/41xxx/CVE-2026-41407.json"},{"type":"ADVISORY","url":"https://github.com/openclaw/openclaw/security/advisories/GHSA-jj6q-rrrf-h66h"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-41407"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/openclaw-timing-side-channel-in-shared-secret-comparison"},{"type":"FIX","url":"https://github.com/openclaw/openclaw/commit/be10ecef770a4654519869c3641bbb91087c8c7b"},{"type":"PACKAGE","url":"https://github.com/openclaw/openclaw"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:33.421828427Z"}}
