Descriptions

Spring Security versions 5.1.x prior to 5.1.2 contain an authorization bypass vulnerability during JWT issuer validation. In order to be impacted, the same private key for an honest issuer and a malicious user must be used when signing JWTs. In that case, a malicious user could fashion signed JWTs with the malicious issuer URL that may be granted for the honest issuer.

Spring Security, en versiones 5.1.x anteriores a la 5.1.2 contiene una vulnerabilidad de omisión de autenticación durante la validación del emisor JWT. Para que sufra un impacto, debe emplearse la misma clave privada para un emisor honesto y un usuario malicioso al firmar JWT. En ese caso, un usuario malicioso podría fabricar JWT firmados con la URL del emisor
