{"schemaVersion":3,"id":"CVE-2026-110024","aliases":[],"status":"published","duplicateOf":null,"title":null,"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.","dates":{"published":"2026-10-18T14:31:38.949Z","modified":"2026-10-20T18:40:02.655Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":6.8,"severity":"medium","version":"3.1","versionLabel":"v3.1","source":"CVE.org","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:N","computed":false,"selection":"backend-summary"},"metrics":[{"version":"3.1","versionLabel":"v3.1","source":"CVE.org","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","exploitability":null,"impact":null,"computed":false},{"version":"3.1","versionLabel":"v3.1","source":"NVD","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","exploitability":null,"impact":null,"computed":false}]},"epss":{"probability":0.00188,"percentile":0.07882,"severity":"low","asOf":"2026-10-20T00:00:00.000Z","change":{"pp":null,"baselineDate":null,"baselineScore":null},"history":[{"date":"2026-10-19T00:00:00.000Z","score":0.00188,"percentile":null},{"date":"2026-10-20T00:00:00.000Z","score":0.00188,"percentile":0.07882}],"last30":[{"date":"2026-10-19T00:00:00.000Z","score":0.00188,"percentile":null},{"date":"2026-10-20T00:00:00.000Z","score":0.00188,"percentile":0.07882}]},"kev":{"state":"not-listed","entries":[],"listedCount":0,"totalCatalogs":3,"catalogs":[{"source":"cisa","label":"CISA","listed":false,"entry":null},{"source":"enisa","label":"ENISA","listed":false,"entry":null},{"source":"circl","label":"CIRCL","listed":false,"entry":null}]},"ransomware":{"state":"none-recorded","sources":[]},"exploits":[],"exploitCount":0,"weaknesses":[{"id":"CWE-613","name":"Insufficient Session Expiration","description":"According to WASC, \"Insufficient Session Expiration is when a web site permits an attacker to reuse old session credentials or session IDs for authorization.\"","type":"weakness","status":"Incomplete","abstraction":"Base","likelihoodOfExploit":null,"url":"https://cwe.mitre.org/data/definitions/613.html"}],"affected":[{"vendor":"@fastify/jwt","product":"@fastify/jwt","name":"@fastify/jwt","label":"@fastify/jwt","ecosystem":null,"cpePart":"a","purl":null,"purlType":null,"versions":[{"text":"< 10.2.5","noFixRecorded":false,"fixedIn":null}],"versionsText":"< 10.2.5","eol":null,"hubHref":"/vendor/fastifyjwt/fastifyjwt"}],"affectedCount":1,"eol":{"hasEol":false,"count":0},"references":[{"url":"https://github.com/fastify/fastify-jwt/security/advisories/GHSA-f5gh-84pj-v2pg","label":"github.com/fastify/fastify-jwt/security/advisories/GHSA-f5gh-84pj-v2pg","hostname":"github.com","tags":[]},{"url":"https://cna.openjsf.org/security-advisories.html","label":"cna.openjsf.org/security-advisories.html","hostname":"cna.openjsf.org","tags":[]}],"lineage":{"upstream":[],"downstream":[],"duplicates":[],"related":[]},"timeline":[{"kind":"published","date":"2026-10-18T14:31:38.949Z","label":"Published","detail":"Vulnerability first disclosed.","source":null},{"kind":"modified","date":"2026-10-20T18:40:02.655Z","label":"Last modified","detail":"Vulnerability information updated.","source":null}],"risk":{"score":27,"level":"medium","profile":"Default","thresholds":{"critical":75,"high":50,"medium":25,"low":10}},"meta":{"dataAsOf":"2026-10-21T13:48:02.451Z","stale":false,"partial":false}}
