{"id":"CVE-2026-41907","summary":"uuid: Missing buffer bounds check in `v3`/`v5`/`v6` when `buf` is provided","details":"uuid is for the creation of RFC9562 (formerly RFC4122) UUIDs. 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.","aliases":["CVE-2026-41988","GHSA-w5hq-g745-h8pq"],"modified":"2026-06-18T03:57:44.763838058Z","published":"2026-04-24T18:09:24.744Z","related":["CGA-cfw7-cq6w-m5hj"],"database_specific":{"cwe_ids":["CWE-787","CWE-823"],"cna_assigner":"GitHub_M","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/41xxx/CVE-2026-41907.json"},"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"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/uuidjs/uuid","events":[{"introduced":"0"},{"fixed":"7269a96c12a55a745bd4a7812c01cfd385ec6c46"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"11.1.1"},{"last_affected":"12.0.0"},{"last_affected":"13.0.0"}],"cpe":["cpe:2.3:a:uuidjs:uuid:*:*:*:*:*:node.js:*:*","cpe:2.3:a:uuidjs:uuid:12.0.0:*:*:*:*:node.js:*:*","cpe:2.3:a:uuidjs:uuid:13.0.0:*:*:*:*:node.js:*:*"],"source":["CPE_RANGE","CPE_STRING"]}}],"versions":["v11.1.0","v11.0.5","v11.0.4","v11.0.3","v11.0.2","v11.0.1","v9.0.0","v8.3.2","v8.3.1","v8.3.0","v8.2.0","v8.1.0","v8.0.0","v7.0.3","v7.0.2","v7.0.1","v7.0.0","v3.4.0","v3.3.3","v3.3.2","v3.3.1","v3.1.0","v3.0.1","v1.4.3","v1.4.2","v1.4.1","v1.4.0","v1.3.3","v1.3.2","v1.3.1","v1.3","v1.2","v1.1","v1.0"],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-41907.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U"}]}
