Technical details

The plugin fails to properly sanitize and escape the 'display_name' parameter, allowing authenticated attackers (subscriber or higher) to inject stored XSS payloads via comments. The malicious script is persisted in the wp_comments.comment_author field and executes in the context of any page displaying that comment, independent of subsequent changes to the attacker's account.
