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.","state":0,"publishedAt":"2026-10-18T14:31:38.949+00:00","modifiedAt":"2026-10-20T18:40:02.655+00:00","affected":[{"ecosystem":"Vendor product","name":"@fastify/jwt","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"@fastify/jwt\",\n                    \"product\": \"@fastify/jwt\",\n                    \"defaultStatus\": \"unaffected\",\n                    \"versions\": [\n                        {\n                            \"versionType\": \"semver\",\n                            \"status\": \"affected\",\n                            \"version\": \"0\",\n                            \"lessThan\": \"10.2.5\"\n                        },\n                        {\n                            \"versionType\": \"semver\",\n                            \"status\": \"unaffected\",\n                            \"version\": \"10.2.5\"\n                        }\n                    ],\n                    \"packageURL\": \"pkg:npm/@fastify/jwt\"\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:N","score":6.8,"severity":"MEDIUM"}],"references":["https://github.com/fastify/fastify-jwt/security/advisories/GHSA-f5gh-84pj-v2pg","https://cna.openjsf.org/security-advisories.html"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-110024","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-110024","identifiers":["CVE-2026-110024"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
