In ftp-srv before versions 2.19.6, 3.1.2, and 4.3.4 are vulnerable to Server-Side Request Forgery. The PORT command allows arbitrary IPs which can be used to cause the server to make a connection elsewhere. A possible workaround is blocking the PORT through the configuration. This issue is fixed in version2 2.19.6, 3.1.2, and 4.3.4. More information can be found on the linked advisory.","published":"2020-08-17T22:15:12.627Z","modified":"2026-08-27T08:13:51.798683Z","cvss":{"score":9.1,"severity":"CRITICAL","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[{"ecosystem":"npm","name":"ftp-srv","fixedVersion":"2.19.6"},{"ecosystem":"npm","name":"ftp-srv","fixedVersion":"3.1.2"},{"ecosystem":"npm","name":"ftp-srv","fixedVersion":"4.3.4"}],"fix":{"url":"https://github.com/autovance/ftp-srv/commit/e449e75219d918c400dec65b4b0759f60476abca","label":"autovance/ftp-srv@e449e75"},"references":[{"type":"ADVISORY","url":"https://www.npmjs.com/package/ftp-srv"},{"type":"FIX","url":"https://github.com/autovance/ftp-srv/commit/e449e75219d918c400dec65b4b0759f60476abca"},{"type":"FIX","url":"https://github.com/autovance/ftp-srv/security/advisories/GHSA-jw37-5gqr-cf9j"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-27T08:13:51.798683Z"}}
