Prior to 4.12.18, improper validation of the JWT NumericDate claims exp, nbf, and iat in hono/utils/jwt allows tokens with non-spec-compliant claim values to silently bypass time-based checks. This issue is not exploitable by an anonymous attacker; it only manifests when a malformed claim value reaches verify() \u2014 typically when the application itself issues such tokens, or when the signing key is otherwise under attacker control. This vulnerability is fixed in 4.12.18."}], "lastModified": "2026-05-13T18:21:48.107", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:hono:hono:*:*:*:*:*:node.js:*:*", "vulnerable": true, "matchCriteriaId": "5AB1A6FC-8475-4A23-9E63-46F3E6C5D264", "versionEndExcluding": "4.12.18"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
