Specifically, the package fails to classify the reserved IP address space 224.0.0.0/4 (Multicast) as invalid. This oversight allows attackers to craft requests targeting these multicast addresses.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:L/VA:N/SC:N/SI:N/SA:N/E:P","score":7.8},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N","score":5.3},"cwes":["CWE-918"],"references":["https://gist.github.com/lirantal/2976840639df824cb3abe60d13c65e04","https://github.com/felippe-regazio/ssrfcheck/commit/9507b49fd764f2a1a1d1e3b9ee577b7545e6950e","https://github.com/felippe-regazio/ssrfcheck/issues/5","https://security.snyk.io/vuln/SNYK-JS-SSRFCHECK-9510756"],"products":["felipperegazio:ssrf_check"],"source":"nvd","synced_at":"2026-10-19T22:05:46.678065081+00:00"},"epss":{"cve":"CVE-2025-8267","score":0.00535,"percentile":0.45158,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-p4hc-9pjh-55c8","url":"https://osv.dev/vulnerability/GHSA-p4hc-9pjh-55c8","summary":"ssrfcheck: SSRF Bypass Caused by Failure to Classify Reserved IP Address Space as Invalid","modified":"2026-05-05T20:56:27.127177Z","packages":[{"ecosystem":"npm","name":"ssrfcheck","purl":"pkg:npm/ssrfcheck","ranges":["<1.2.0"],"fixed":["1.2.0"]}]}],"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).
