| summary: Authorization bypass in github.com/dgrijalva/jwt-go |
| description: |- |
| If a JWT contains an audience claim with an array of strings, rather than a |
| single string, and MapClaims.VerifyAudience is called with req set to false, |
| then audience verification will be bypassed, allowing an invalid set of |
| audiences to be provided. |
