Prior to 14.0.0, v3, v5, and v6 accept external output buffers but do not reject out-of-range writes (small buf or large offset). This allows silent partial writes into caller-provided buffers. This vulnerability is fixed in 14.0.0.","published":"2026-04-24T18:09:24.744Z","modified":"2026-08-12T03:51:08.384504080Z","cvss":null,"epss":{"score":0.00337,"percentile":0.26481,"asOf":"2026-08-13"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"uuid","fixedVersion":"11.1.1"},{"ecosystem":"npm","name":"uuid","fixedVersion":"12.0.1"},{"ecosystem":"npm","name":"uuid","fixedVersion":"13.0.1"}],"fix":null,"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/41xxx/CVE-2026-41907.json"},{"type":"ADVISORY","url":"https://github.com/uuidjs/uuid/security/advisories/GHSA-w5hq-g745-h8pq"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-41907"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:08.384504080Z"}}
