-------------------------------------------------------------------
I created a test PR for this here: [https://github.com/apache/struts/pull/743]
However:
Having done some further testing, I don't believe this mitigation to be
necessary. There isn't anything inherently dangerous about just loading the
class. Class members are still subject to {{SecurityMemberAccess}} checks and
static fields and methods can be blocked with the following options.
{{struts.ognl.allowStaticFieldAccess=false}}
{{{}struts.ognl.allowStaticMethodAccess=false{}}}{{{}{}}}
Given that, I am going to close this card.
