This is an incomplete fix of CVE-2026-48930, which only covered dns.lookup() and the net/tls host options.\r\n\r\nBecause the name is passed to c-ares as a C string, resolving attacker.example\\0.trusted.example queries attacker.example and returns its records without any error. Applications that validate a hostname, for example against a domain allowlist, and then resolve it with dns.resolve*() can act on records for a different name than the one they validated.\r\n\r\nThis vulnerability affects Node.js 26.x, 24.x, and 22.x.","epss":{"date":"2026-11-02","percentile":0.40527,"score":0.00468},"exploits":[],"kev":null,"metrics":[{"score":7.4,"severity":"high","source":"CNA: hackerone","vector":"CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N","version":"3.0"},{"score":7.4,"severity":"high","source":"NVD: support@hackerone.com","vector":"CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N","version":"3.0"}],"modifiedAt":1793636243480,"publishedAt":1792772105831,"references":[{"source":"CNA: hackerone","tags":[],"url":"https://nodejs.org/en/blog/vulnerability/october-2026-security-releases"},{"source":"support@hackerone.com","tags":[],"url":"https://nodejs.org/en/blog/vulnerability/october-2026-security-releases"}],"remediation":[],"revision":"0a2058e37e29ad0570635f94b94afd1886c161a69a91b894d05606280dd31dce","sources":[{"modifiedAt":1793634714058,"name":"CNA: hackerone","retrievedAt":1793635705671,"url":"https://www.cve.org/CVERecord?id=CVE-2026-105482"},{"modifiedAt":1793636243480,"name":"NVD","retrievedAt":1793643423366,"url":"https://nvd.nist.gov/vuln/detail/CVE-2026-105482"},{"modifiedAt":null,"name":"FIRST EPSS","retrievedAt":1793635727763,"url":"https://api.first.org/data/v1/epss?cve=CVE-2026-105482"}],"ssvc":{"assessedAt":1793634693530,"automatable":"no","exploitation":"none","source":"ADP: CISA-ADP","technicalImpact":"total"},"status":"published","title":"CVE-2026-105482","updatedAt":1793643423366}
