{"id":"CVE-2026-41362","aliases":["GHSA-fqrj-m88p-qf3v"],"url":"https://o3.security/vulnerability/CVE-2026-41362","summary":"OpenClaw 2026.2.19 through 2026.3.30 - Webhook Replay Dedupe Cache Event Suppression via Shared Authentication","details":"## Summary\n\nBefore OpenClaw 2026.3.31, the Zalo webhook replay-dedupe cache was shared across authenticated webhook targets and keyed too broadly. In multi-account deployments, a replay seen on one account could suppress a legitimate event on another account if `event_name` and `message_id` matched.\n\n## Impact\n\nAn attacker who controlled one authenticated Zalo webhook path in a multi-account gateway deployment could cause silent message suppression on a different Zalo account sharing that gateway. This was an availability issue; it did not provide cross-account authentication or data access.\n\n## Affected Packages / Versions\n\n- Package: `openclaw` (npm)\n- Affected versions: `>= 2026.2.19, < 2026.3.31`\n- Patched versions: `>= 2026.3.31`\n- Latest published npm version: `2026.4.1`\n\n## Fix Commit(s)\n\n- `4d038bb242c11f39e45f6a4bde400e5fd42e4ebf` — scope webhook replay dedupe per target\n- `7cea7c29705b188b464cc9cdc107c275b94b2a72` — follow-up hardening to scope replay dedupe by path and account\n\n## Release Process Note\n\nThe initial fix shipped in OpenClaw `2026.3.31` on March 31, 2026. The current published npm release `2026.4.1` from April 1, 2026 also contains follow-up hardening for the same surface.\n\nThanks @nexrin for reporting.","published":"2026-04-27T23:24:26.193Z","modified":"2026-10-28T02:30:42.624088628Z","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"openclaw","fixedVersion":"2026.3.31"}],"fix":{"url":"https://github.com/openclaw/openclaw/commit/4d038bb242c11f39e45f6a4bde400e5fd42e4ebf","label":"openclaw/openclaw@4d038bb"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/41xxx/CVE-2026-41362.json"},{"type":"ADVISORY","url":"https://github.com/openclaw/openclaw/security/advisories/GHSA-fqrj-m88p-qf3v"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-41362"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/openclaw-webhook-replay-dedupe-cache-event-suppression-via-shared-authentication"},{"type":"FIX","url":"https://github.com/openclaw/openclaw/commit/4d038bb242c11f39e45f6a4bde400e5fd42e4ebf"},{"type":"FIX","url":"https://github.com/openclaw/openclaw/commit/7cea7c29705b188b464cc9cdc107c275b94b2a72"},{"type":"PACKAGE","url":"https://github.com/openclaw/openclaw"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-10-28T02:30:42.624088628Z"}}
