Cross-site scripting (XSS) vulnerability in the Wordfence Security plugin before 5.1.5 for WordPress allows remote attackers to inject arbitrary web script or HTML via the val parameter to whois.php.

The Wordfence plugin 7.2.3 for WordPress allows XSS via a unique attack vector. NOTE: It has been asserted that this is not a valid vulnerability in the context of the Wordfence WordPress plugin as the firewall rules are not maintained as part of the Wordfence software but rather it is a set of rules hosted on vendor servers and pushed to the plugin with no versioning associated. Bypassing a WAF rule doesn't make a WordPress site vulnerable (speaking in terms of software vulnerabilities)

The Wordfence Security – Firewall & Malware Scan plugin for WordPress is vulnerable to Stored Cross-Site Scripting in versions up to and including 7.6.0 via a setting on the options page due to insufficient escaping on the stored value. This makes it possible for authenticated users, with administrative privileges, to inject malicious web scripts into the setting that executes whenever a user accesses a page displaying the affected setting on sites running a vulnerable version.
