The Wordfence Security Plugin for WordPress is prone to following vulnerabilities:
1. Multiple HTML-Injection vulnerabilities
2. Multiple Security Bypass vulnerabilities
Successful exploits of these issues allow the attacker-supplied HTML and script code to run in the context of the affected browser potentially allowing the attacker to steal cookie-based authentication credentials or control how the site is rendered to the user, or to bypass security mechanisms.
Wordfence Security Plugin 5.2.3 is vulnerable; other versions may also be affected
