{"id":"CVE-2026-110024","url":"https://www.cyber-defence.io/tools/cve/CVE-2026-110024","generatedAt":"2026-10-28T01:12:07.763Z","title":"@fastify/jwt is a JWT utility plugin for Fastify.","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.","published":"2026-10-18T15:16:51.000Z","lastModified":"2026-10-20T19:17:29.000Z","status":"Awaiting Analysis","sourceIdentifier":"ce714d77-add3-4f53-aff5-83d477b104bb","cvss":{"version":"3.1","score":6.8,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:N"},"cwe":["CWE-613"],"affected":[],"epss":{"score":0.00188,"percentile":0.08285,"date":"2026-10-26","history":[{"date":"2026-10-19","score":0.00188,"percentile":0.0787}]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"low","text":"Lower severity and a low EPSS score (0.19%).
