Wordfence v5.2.3 suffers from multiple vulnerabilities including 2 stored XSS, insufficient logging of requests, being able to bypass the throttling feature (designed to limit scraping) and being able to bypass the exploit detection feature. All of these appear to be the result of a lack of understanding of PHP superglobals.
And we’re back. Check out Part 1 if you haven’t yet. Much like before, developers of these plugins have not been contacted in advance. These vulnerabilities were trivial to find and as you can see from these vulnerabilities and others that have been disclosed in the past few months, popular =/= secure. More vulnerabilities will be posted as time permits.
This post contains information on vulnerabilities for 7 (at least somewhat) popular wordpress plugins. All of these vulnerabilities were trivial to discover (and are trivial to fix). The state of wordpress plugin security is very sad indeed. None of the developers were contacted in advance of this post (except where otherwise noted). Additional vulnerabilities will be posted as time permits.
