Apache APISIX: cas-auth login CSRF / session injection issue

Cross-Site Request Forgery (CSRF) vulnerability in the cas-auth plugin under default configurations.

This defect allows a remote attacker that manages to send a victim to a webpage controlled by them can cause the victim's browser to become authenticated as a different identity.

Actions the victim takes upstream are then attributed to attackers identity.

This issue affects Apache APISIX: from 3.0.0 through 3.16.0.

Users are recommended to upgrade to version 3.17.0, which fixes the issue.
