| summary: Incorrect handling of credential expiry in github.com/nats-io/jwt |
| description: |- |
| The AccountClaims.IsRevoked and Export.IsRevoked functions improperly validate |
| expired credentials using the current system time rather than the issue time of |
| the JWT to be tested. |
| |
| These functions cannot be used properly. Newer versions of the jwt package |
| provide an IsClaimRevoked method which performs correct validation. In these |
| versions, the IsRevoked method always return true. |
