TL;DR

The optional extended Special:Search profile writes the search parameter into the page as raw HTML. A crafted search URL reflects that value into the response, leading to cross-site scripting. The fix escapes the query string before rendering the profile.

Who does this affect?

You are affected if you are using a version that falls within the vulnerable range and the extended search profile is enabled.
