hono is vulnerable to Improper Input Validation
38
Low Risk
This Affects:
honoTL;DR
JWT verification accepts malformed NumericDate claims for exp, nbf, and iat in some non-compliant value forms. Falsy, non-finite, or non-numeric values can bypass intended time-based checks instead of being rejected. This weakens token lifetime and not-before validation when malformed claims are introduced. The fix enforces strict NumericDate validation and rejects invalid claim types and values during verify-time checks.
