## Description

CMAK through 3.0.0.6 fails to install a cross-site request forgery filter, allowing attackers to perform state-changing actions on behalf of authenticated operators. Attackers can craft hidden forms that submit to destructive endpoints like topic deletion and cluster configuration changes, leveraging the operator's HTTP Basic authentication credentials or play-basic-authentication cookie without SameSite protection.
