WPBakery Page Builder is a page design plugin for WordPress that lets users build website layouts visually. Authenticated attackers with subscriber-level access or higher can inject malicious scripts into pages through user profile fields, which execute when other users view pages containing a Basic Grid with Post Author elements linked to the attacker's posts. This could allow an attacker to steal credentials, perform unauthorized actions, or deface website content.
