{"id":"GHSA-jj6q-rrrf-h66h","summary":"OpenClaw: Shared-secret comparison call sites leaked length information through timing","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: `\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- `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.","aliases":["CVE-2026-41407"],"modified":"2026-05-06T02:51:08.214407Z","published":"2026-04-07T18:16:03Z","database_specific":{"github_reviewed":true,"github_reviewed_at":"2026-04-07T18:16:03Z","nvd_published_at":"2026-04-28T19:37:44Z","cwe_ids":["CWE-208"],"severity":"MODERATE"},"references":[{"type":"WEB","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":"WEB","url":"https://github.com/openclaw/openclaw/commit/be10ecef770a4654519869c3641bbb91087c8c7b"},{"type":"PACKAGE","url":"https://github.com/openclaw/openclaw"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/openclaw-timing-side-channel-in-shared-secret-comparison"}],"affected":[{"package":{"name":"openclaw","ecosystem":"npm","purl":"pkg:npm/openclaw"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"2026.4.2"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/04/GHSA-jj6q-rrrf-h66h/GHSA-jj6q-rrrf-h66h.json","last_known_affected_version_range":"\u003c= 2026.4.1"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:N"},{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N"}]}
