style, class, linkstyle & linkclass parameters allow XSS
Closed, ResolvedPublic


The WikiCategoryTagCloud extension doesn't properly validate the values of the aforementioned four XML-style extension parameters.

Proper fix is to call htmlspecialchars() with ENT_QUOTES as the 2nd param (class & linkclass parameters) or Sanitizer::checkCss() (linkstyle & style parameters).
