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.","categories":["Runtimes & languages"],"product":"node","vendor":"nodejs","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-105482","source_modified_at":"2026-10-23T16:15:05.831Z","fetched_at":"2026-10-23T18:42:43.628194Z","product":"node","vendor":"nodejs","versions":[{"version":"22.23.3","status":"affected","lessThanOrEqual":"22.23.3","versionType":"semver"},{"version":"24.22.0","status":"affected","lessThanOrEqual":"24.22.0","versionType":"semver"},{"version":"26.12.0","status":"affected","lessThanOrEqual":"26.12.0","versionType":"semver"}],"defaultStatus":"unaffected"}],"fixed_versions":[],"cvss":7.4,"severity":"High","kev":{"listed":false},"epss":{"probability":null,"percentile":null,"score_date":null},"published_at":"2026-10-23T16:15:05.831Z","modified_at":"2026-10-23T16:15:05.831Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-105482","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23T16:15:05.831Z"}],"sources":["CVE List"],"references":[{"source":"CVE List","url":"https://nodejs.org/en/blog/vulnerability/october-2026-security-releases"}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":"vendor and product","confidence":"heuristic","reviewed":false},"change_timestamp":"2026-10-23T16:15:05.831Z","content_hash":"836c741c37fbbb461b54e3928a21232d3cdec64aea2a692c234e1930aa134499"}}
