WordPress Plugin WordPress Landing Page-Squeeze Page-Responsive Landing Page Builder Free-WP Lead Plus X is prone to multiple vulnerabilities, including cross-site scripting and cross-site request forgery vulnerabilities. Exploiting these issues could allow an attacker to execute arbitrary script code in the browser of an unsuspecting user in the context of the affected site, allowing the attacker to steal cookie-based authentication credentials and launch other attacks, or to perform certain administrative actions and gain unauthorized access to the affected application. WordPress Plugin WordPress Landing Page-Squeeze Page-Responsive Landing Page Builder Free-WP Lead Plus X version 0.98 is vulnerable; prior versions may also be affected.
The XSSes have been patched in version 0.99. Either edit the source code to ensure that CSRF protection is implemented with Nonce-like mechanism or disable the plugin until a fix is available for the CSRF.
