Summary

Enguerran discovered a way to store payloads that would trigger XSS in the MediaElement Flash and Silverlight files that were bundled with WordPress.

We coordinated a fix with MediaElement, and moved the files from WordPress Core to an optional plugin, since most users no longer needed them.
