We announced the same few months ago [1] and there was just one
release (Struts 2.3.35) that missed the thing [2]. And we won't be
releasing a new version just because some of dependencies was
discovered to be vulnerable. And yes, we missed that the Struts 2.3.35
and Struts 2.3.36 are using vulnerable library.

There is a known vulnerability that affects 1.3.2 and prior versions
of commons-fileupload [3]. It's a RCE attack not a DoS.
