How to fix?

Upgrade org.apache.myfaces.core:myfaces-core-project to version 2.0.25, 2.2.14, 2.3.8, 2.3-next-M5, 3.0.0 or higher.


org.apache.myfaces.core:myfaces-core-project is a MyFaces implementation of the JavaServer Faces 2.3 specification, and consists of an API module (javax.faces.* classes) and an implementation module (org.apache.myfaces.* classes).

Affected versions of this package are vulnerable to Cross-site Request Forgery (CSRF). In the default configuration, Apache MyFaces Core uses cryptographically weak implicit and explicit cross-site request forgery (CSRF) tokens. Due to that limitation, it is possible (although difficult) for an attacker to calculate a future CSRF token value and to use that value to trick a user into executing unwanted actions on an application.
