Description
WordPress Plugin WP Statistics is prone to multiple vulnerabilities, including cross-site scripting and SQL injection 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, or to compromise the application, access or modify data, or exploit latent vulnerabilities in the underlying database. WordPress Plugin WP Statistics version 13.1.5 is vulnerable; prior versions may also be affected.
Remediation
Update to plugin version 13.1.6 or latest
