I contacted CPA Canada in early 2017 about XSS and some other issues on
cert.webtrust.org.

They did not fix the issues but stated:

As of April 2018 the issues were still unfixed. I wonder if the limited
access is part of those security "enhancements"?

PS: This change also breaks "legitimate" WebTrust Seal links when either
the website or the web browser is configured to not send the "Referer"
header.
