Description
wpDiscuz before 7.6.47 contains a shortcode injection vulnerability that allows attackers to execute arbitrary shortcodes by including them in comment content sent via email notifications. Attackers can inject shortcodes like [contact-form-7] or [user_meta] in comments, which are executed server-side when the WpdiscuzHelperEmail class processes notifications through do_shortcode() before wp_mail().
