Prior to 3.2.1, RequestFilteringHttpAgent and RequestFilteringHttpsAgent synchronously threw from createConnection when rejecting a literal private-IP host such as 169.254.169.254 or 127.0.0.1. Because Node.js http.request and http.get expect connection failures to be delivered asynchronously, the throw bypassed req.on('error') and became an uncaught exception that could terminate the application process. Hostnames resolved through the asynchronous lookup path were not affected by this error-delivery asymmetry. This issue is fixed in version 3.2.1.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","score":7.5},"cwes":["CWE-248"],"references":["https://github.com/azu/request-filtering-agent/commit/9d12561064524807fc399158eaa5bd7a40dd8cd0","https://github.com/azu/request-filtering-agent/releases/tag/v3.2.1","https://github.com/azu/request-filtering-agent/security/advisories/GHSA-r3r9-wp5j-pq5g","https://github.com/azu/request-filtering-agent/security/advisories/GHSA-r3r9-wp5j-pq5g"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:56:02.509636177+00:00"},"epss":{"cve":"CVE-2026-62985","score":0.00564,"percentile":0.46876,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-r3r9-wp5j-pq5g","url":"https://osv.dev/vulnerability/GHSA-r3r9-wp5j-pq5g","summary":"request-filtering-agent: Synchronous throw from createConnection() for literal private-IP hosts bypasses req.on('error'), crashing the Node.js process","modified":"2026-09-22T20:00:05.170933615Z","packages":[{"ecosystem":"npm","name":"request-filtering-agent","purl":"pkg:npm/request-filtering-agent","ranges":["<3.2.1"],"fixed":["3.2.1"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
