This is due to insufficient output escaping in the ctdb_filter_comment_author_name() callback hooked to get_comment_author_link, which interpolates the raw user_url value into a single-quoted href attribute without esc_url() or esc_attr(). This makes it possible for authenticated attackers, with subscriber-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses a Discussion Board topic containing the attacker's reply."}], "lastModified": "2026-10-31T07:16:34.070", "sourceIdentifier": "security@wordfence.com"}
