Wordfence Firewall Blocks Bizarre Large-Scale XSS Campaign

The Wordfence Threat Intelligence team has been monitoring an increase in attacks targeting a Cross-Site Scripting vulnerability in Beautiful Cookie Consent Banner, a WordPress plugin installed on over 40,000 sites. The vulnerability, which was fully patched in January in version 2.10.2, offers unauthenticated attackers the ability to add malicious JavaScript to a website, potentially allowing redirects to malvertizing sites as well as the creation of malicious admin users, both of which are appealing use cases for attackers.
