{"id":"BIT-node-2026-105482","details":"A flaw in Node.js DNS resolution allows hostnames containing a NUL byte to be silently truncated by the dns.resolve*() functions and dns.reverse(). 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.","aliases":["BIT-node-min-2026-105482","CVE-2026-105482"],"modified":"2026-10-29T10:56:11.695172887Z","published":"2026-10-29T08:55:53.773Z","database_specific":{"cpes":["cpe:2.3:a:nodejs:node.js:*:*:*:*:*:*:*:*"],"severity":"High"},"references":[{"type":"WEB","url":"https://nodejs.org/en/blog/vulnerability/october-2026-security-releases"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-105482"}],"affected":[{"package":{"name":"node","ecosystem":"Bitnami","purl":"pkg:bitnami/node"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"22.23.4"},{"introduced":"23.0.0"},{"fixed":"24.22.1"},{"introduced":"25.0.0"},{"fixed":"26.12.1"}]}],"database_specific":{"source":"https://github.com/bitnami/vulndb/tree/main/data/node/BIT-node-2026-105482.json"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N"}]}],"schema_version":"1.9.2"}
