Technical details

The plugin fails to properly escape the user_url profile field when rendering comment author links in the ctdb_filter_comment_author_name() callback. An authenticated subscriber can inject arbitrary HTML and JavaScript into the website URL field, which is then inserted unescaped into single-quoted href attributes on public forum pages. The vulnerability is triggered whenever another user views a Discussion Board topic containing the attacker's comment.
