{"id":"CVE-2026-110024","summary":"@fastify/jwt vulnerable to missing token expiration when per-call options drop global defaults","details":"@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.","aliases":["GHSA-f5gh-84pj-v2pg"],"modified":"2026-10-21T10:30:56.731932445Z","published":"2026-10-18T14:31:38.949Z","database_specific":{"cna_assigner":"openjs","cwe_ids":["CWE-613"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/110xxx/CVE-2026-110024.json"},"references":[{"type":"ADVISORY","url":"https://cna.openjsf.org/security-advisories.html"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/110xxx/CVE-2026-110024.json"},{"type":"ADVISORY","url":"https://github.com/fastify/fastify-jwt/security/advisories/GHSA-f5gh-84pj-v2pg"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-110024"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/fastify/fastify-jwt","events":[{"introduced":"0"},{"fixed":"547597925b98db2ab7e5081a5b372f93f1709faf"}],"database_specific":{"extracted_events":[{"source":"AFFECTED_FIELD","strategy":"StandardRange","range":[{"introduced":"0"},{"fixed":"10.2.5"}]}]}}],"versions":["v10.2.4","v10.2.3","v10.2.2","v10.2.1","v10.2.0","v10.1.0","v10.0.0","v9.1.0","v9.0.4","v9.0.3","v9.0.2","v9.0.1","v9.0.0","v8.0.1","8.0.1","v8.0.0","v7.2.4","v7.2.3","v7.2.2","v7.2.1","v7.2.0","v7.1.0","v7.0.0","v6.7.1","v6.7.0","v6.6.0","v6.3.1","v6.5.0","v6.4.0","v6.3.3","v6.3.2","v6.3.0","v6.2.1","v6.2.0","v6.1.0","v6.0.0","v5.0.1","v5.0.0","v4.1.3","v4.1.2","v4.1.1","v4.1.0","v4.0.1","v4.0.0","v3.2.1","v3.2.0","v3.1.0","v3.0.1","v3.0.0","v2.5.0","v2.4.0","v2.3.0","v2.2.0","v2.1.3","v2.1.2","v2.1.1","v2.1.0","v1.3.1","v2.0.0","v1.3.0","v1.2.1","v1.2.0","v1.1.0","v1.0.0","v0.10.0","v0.9.6","v0.9.5","v0.9.4","v0.9.3","v0.9.2","v0.9.1","v0.9.0","v0.8.1","v0.8.0","v0.7.0","v0.6.0","v0.5.0","v0.4.0","v0.3.0","v0.2.1","v0.2.0","v0.1.1","v0.1.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-110024.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:N"}]}
