already to 7.0.104 which is not affected by that vulnerability.

So the solution is to upgrade the CA Access Gateway (SPS) to 12.8SP4.

About the Web Agent Option Pack, you just have to patch the Tomcat
version you run as we don't provide the Tomcat version. It's on your
responsability.

I've checked and Web Agent Option Pack 12.52SP1CR10 64bit is supported
on Tomcat 8.5 :
