{"id":"CVE-2025-8267","details":"Versions of the package ssrfcheck before 1.2.0 are vulnerable to Server-Side Request Forgery (SSRF) due to an incomplete denylist of IP address ranges. 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.","aliases":["GHSA-p4hc-9pjh-55c8"],"modified":"2026-09-13T11:45:14.645241916Z","published":"2025-07-28T05:00:00.992Z","database_specific":{"cna_assigner":"snyk","cwe_ids":["CWE-918"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/8xxx/CVE-2025-8267.json","unresolved_ranges":[{"extracted_events":[{"fixed":"1.2.0"}],"source":"AFFECTED_FIELD"},{"source":"DESCRIPTION","extracted_events":[{"fixed":"1.2.0"}]}]},"references":[{"type":"WEB","url":"https://gist.github.com/lirantal/2976840639df824cb3abe60d13c65e04"},{"type":"WEB","url":"https://security.snyk.io/vuln/SNYK-JS-SSRFCHECK-9510756"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/8xxx/CVE-2025-8267.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-8267"},{"type":"REPORT","url":"https://github.com/felippe-regazio/ssrfcheck/issues/5"},{"type":"FIX","url":"https://github.com/felippe-regazio/ssrfcheck/commit/9507b49fd764f2a1a1d1e3b9ee577b7545e6950e"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/felippe-regazio/ssrfcheck","events":[{"introduced":"0"},{"fixed":"9507b49fd764f2a1a1d1e3b9ee577b7545e6950e"}],"database_specific":{"source":"REFERENCES"}}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2025-8267.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:H/VI:L/VA:N/SC:N/SI:N/SA:N/E:P"}]}
