Prior to versions 7.4.1 and 6.0.1, @fastify/multipart may experience denial of service due to a number of situations in which an unlimited number of parts are accepted. This includes the multipart body parser accepting an unlimited number of file parts, the multipart body parser accepting an unlimited number of field parts, and the multipart body parser accepting an unlimited number of empty parts as field parts. This is fixed in v7.4.1 (for Fastify v4.x) and v6.0.1 (for Fastify v3.x). There are no known workarounds.","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-770"],"references":["https://github.com/fastify/fastify-multipart/commit/85be81bedf5b29cfd9fe3efc30fb5a17173c1297","https://github.com/fastify/fastify-multipart/releases/tag/v6.0.1","https://github.com/fastify/fastify-multipart/releases/tag/v7.4.1","https://github.com/fastify/fastify-multipart/security/advisories/GHSA-hpp2-2cr5-pf6g","https://hackerone.com/reports/1816195"],"products":["fastify:fastify-multipart"],"source":"nvd","synced_at":"2026-10-19T21:37:38.595364862+00:00"},"epss":{"cve":"CVE-2023-25576","score":0.01463,"percentile":0.73621,"date":"2026-11-01"},"kev":null,"osv":[{"id":"GHSA-hpp2-2cr5-pf6g","url":"https://osv.dev/vulnerability/GHSA-hpp2-2cr5-pf6g","summary":"Denial of service due to unlimited number of parts","modified":"2023-11-08T04:11:52.480212Z","packages":[{"ecosystem":"npm","name":"@fastify/multipart","purl":"pkg:npm/%40fastify/multipart","ranges":["<6.0.1"],"fixed":["6.0.1"]},{"ecosystem":"npm","name":"@fastify/multipart","purl":"pkg:npm/%40fastify/multipart","ranges":[">=7.0.0 <7.4.1"],"fixed":["7.4.1"]}]}],"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).
