What it is

The Comments – wpDiscuz plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the guest commenter 'Website' field in versions up to, and including, 7.6.56 This is due to insufficient output escaping in the getCommentAuthor() function, which interpolates the stored comment_author_url value directly into single-quoted HTML attributes without applying esc_url() or esc_attr(). This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
