  "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.",
