Q: Who can exploit this issue?

Any authenticated WordPress user with the Contributor role or a higher-privileged role can exploit it, provided they can supply a template body processed by the plugin's bundled templating engine.

Successful exploitation allows the attacker to execute arbitrary PHP code on the WordPress server. This is server-side remote code execution.

Q: Which versions are affected?
