Technical details
The /search endpoint fails to properly escape backslashes in user-supplied query parameters before inserting them into JavaScript string context in search.html. An attacker can inject a backslash-quote sequence to break out of the string and inject arbitrary JavaScript, which executes in the browser of any authenticated user who follows a crafted link. The vulnerability requires user interaction (clicking a link) but does not require authentication from the attacker.
