CVSS 3.1
7.5 highCVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:NCVE-2020-26160
High (7.5) in jwt-go project jwt-go. EPSS 2.2% chance of exploitation in the next 30 days. Fixed in github.com/dgrijalva/jwt-go/v4 4.0.0-preview1.
jwt-go before 4.0.0-preview1 allows attackers to bypass intended access restrictions in situations with []string{} for m["aud"] (which is allowed by the specification). Because the type assertion fails, "" is the value of aud. This is a security problem if the JWT token is presented to a service that lacks its own audience check.
