Description
SearchHighlighter::removeWiki() uses a regex to remove html from snippets. The regex - /<\/?[^>]+>/ assumes that html is well-formed. As a result when using SearchHighlighter::highlightText() as the highlighting method, this can result in an XSS when $wgAdvancedSearchHighlighting is true.
