This vulnerability could be used in combination with others. For example, XSS via Cookie, session fixation or bypass Double-Submit Cookie CSRF protection.
PoC (FireFox)

After sending the request through FireFox this query is saved in cache and using a small trick can be made to work it in another browser.
PoC (Chrome)
Make sure you send this request after FireFox and previous http response contained the header X-Cache: HIT
