{"id":"CVE-2026-54729","summary":"dssrf: any users using 1.1.1.1 DNS is impacted by SSRF","details":"DSSRF is a Node.js library that provides a wide range of utilities and advanced SSRF defense checks. Prior to 1.0.5, is_url_safe can treat localhost as safe when DNS resolver 1.1.1.1 returns NXDOMAIN because dns.resolve4 yields no address and no dns.lookup fallback occurs, allowing server-side request forgery. This issue is fixed in version 1.0.5.","aliases":["GHSA-5846-7qm3-r52j"],"modified":"2026-09-26T03:46:09.302374894Z","published":"2026-07-31T16:58:56.571Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-918"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/54xxx/CVE-2026-54729.json","unresolved_ranges":[{"extracted_events":[{"fixed":"1.0.5"}],"source":"AFFECTED_FIELD"}]},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/54xxx/CVE-2026-54729.json"},{"type":"ADVISORY","url":"https://github.com/HackingRepo/dssrf-js/security/advisories/GHSA-5846-7qm3-r52j"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-54729"},{"type":"FIX","url":"https://github.com/HackingRepo/dssrf-js/commit/668c21792cd1252baf779a176aa652e2b4c0067d"},{"type":"FIX","url":"https://github.com/HackingRepo/dssrf-js/pull/102"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/hackingrepo/dssrf-js","events":[{"introduced":"0"},{"fixed":"668c21792cd1252baf779a176aa652e2b4c0067d"}],"database_specific":{"source":"REFERENCES"}}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-54729.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N"}]}
