XSS in admin's add/change related popup
10+
=======================================
11+
12+
Unsafe usage of JavaScript's ``Element.innerHTML`` could result in XSS in the
13+
admin's add/change related popup. ``Element.textContent`` is now used to
14+
prevent execution of the data.
15+
16+
The debug view also used ``innerHTML``. Although a security issue wasn't
17+
identified there, out of an abundance of caution it's also updated to use
18+
``textContent``.
