In Spring Security, versions 6.1.x prior to 6.1.7 and versions 6.2.x prior to 6.2.2, an application is vulnerable to broken access control when it directly uses the AuthenticationTrustResolver.isFullyAuthenticated(Authentication) method.

Specifically, an application is vulnerable if:

•  The application uses AuthenticationTrustResolver.isFullyAuthenticated(Authentication) directly and a null authentication parameter is passed to it resulting in an erroneous true return value.

​

An application is not vulnerable if any of the following is true:

•  The application does not use AuthenticationTrustResolver.isFullyAuthenticated(Authentication) directly.
•  The application does not pass null to AuthenticationTrustResolver.isFullyAuthenticated
•  The application only uses isFullyAuthenticated via  Method Security https://docs.spring.io/spring-security/reference/servlet/authorization/method-security.html  or  HTTP Request Security https://docs.spring.io/spring-security/reference/servlet/authorization/authorize-http-requests.html
