CVE-2020-26160: Jwt-Go Project Jwt-Go

High severity, CVSS 7.5. EPSS: 2.2% chance of exploitation in the next 30 days.

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.

Affected products

• Jwt-Go Project Jwt-Go: up to and including 3.2.0
