{"id":"CVE-2026-110024","state":"PUBLISHED","title":"@fastify/jwt vulnerable to missing token expiration when per-call options drop global defaults","description":"@fastify/jwt is a JWT utility plugin for Fastify. In versions prior to 10.2.5, the top-level sign and verify methods replace the globally configured defaults with the per-call options instead of merging them, so passing any per-call option silently drops every global default that the call does not restate, including temporal protections such as token expiration and maximum accepted token age. A token signed this way carries no expiration claim and never expires, and verification stops enforcing a configured maximum age, so stale or never-expiring tokens are accepted. The route-level decorators for signing and verifying already merge options and are not affected. The issue is fixed in @fastify/jwt 10.2.5, and users should upgrade to 10.2.5 or later.","publishedAt":"2026-10-18T14:31:38.949Z","updatedAt":"2026-10-20T18:40:02.655Z","severity":{"score":6.8,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:N","source":"openjs"},"assigner":"openjs","products":["@fastify/jwt @fastify/jwt"],"affected":[{"vendor":"@fastify/jwt","product":"@fastify/jwt","packageURL":"pkg:npm/@fastify/jwt","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThan":"10.2.5","versionType":"semver"},{"version":"10.2.5","status":"unaffected","versionType":"semver"}]}],"references":["https://github.com/fastify/fastify-jwt/security/advisories/GHSA-f5gh-84pj-v2pg","https://cna.openjsf.org/security-advisories.html"],"weaknesses":["CWE-613"],"ingestedAt":"2026-10-29T20:10:33.477Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/110xxx/CVE-2026-110024.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-110024","state":"PUBLISHED","datePublished":"2026-10-18T14:31:38.949Z","dateUpdated":"2026-10-20T18:40:02.655Z","assignerShortName":"openjs","assignerOrgId":"ce714d77-add3-4f53-aff5-83d477b104bb","dateReserved":"2026-10-13T15:07:55.688Z"},"containers":{"cna":{"title":"@fastify/jwt vulnerable to missing token expiration when per-call options drop global defaults","descriptions":[{"lang":"en","value":"@fastify/jwt is a JWT utility plugin for Fastify.
