{"id":"CVE-2025-47279","state":"PUBLISHED","title":"undici Denial of Service attack via bad certificate data","description":"Undici is an HTTP/1.1 client for Node.js. Prior to versions 5.29.0, 6.21.2, and 7.5.0, applications that use undici to implement a webhook-like system are vulnerable. If the attacker set up a server with an invalid certificate, and they can force the application to call the webhook repeatedly, then they can cause a memory leak. This has been patched in versions 5.29.0, 6.21.2, and 7.5.0. As a workaound, avoid calling a webhook repeatedly if the webhook fails.","publishedAt":"2025-05-15T17:16:02.738Z","updatedAt":"2026-02-06T19:14:56.281Z","severity":{"score":3.1,"label":"Low","version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:N/I:N/A:L","source":"GitHub_M"},"assigner":"GitHub_M","products":["nodejs undici"],"affected":[{"vendor":"nodejs","product":"undici","versions":[{"version":"< 5.29.0","status":"affected"},{"version":">= 6.0.0, < 6.21.2","status":"affected"},{"version":">= 7.0.0, < 7.5.0","status":"affected"}]}],"references":["https://github.com/nodejs/undici/security/advisories/GHSA-cxrh-j4jr-qwg3","https://github.com/nodejs/undici/issues/3895","https://github.com/nodejs/undici/pull/4088","https://github.com/nodejs/undici/commit/f317618ec28753a4218beccea048bcf89c36db25"],"weaknesses":["CWE-401"],"ingestedAt":"2026-10-29T20:09:23.771Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2025/47xxx/CVE-2025-47279.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2025-47279","state":"PUBLISHED","datePublished":"2025-05-15T17:16:02.738Z","dateUpdated":"2026-02-06T19:14:56.281Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2025-05-05T16:53:10.373Z"},"containers":{"cna":{"title":"undici Denial of Service attack via bad certificate data","descriptions":[{"lang":"en","value":"Undici is an HTTP/1.1 client for Node.js.
