Description
WordPress Plugin GD Star Rating is prone to multiple vulnerabilities, including cross-site request forgery and SQL injection vulnerabilities. Exploiting these issues may allow an attacker to perform certain administrative actions and gain unauthorized access to the affected application or to compromise the application, access or modify data, or exploit latent vulnerabilities in the underlying database. WordPress Plugin GD Star Rating version 1.9.22 is vulnerable; prior versions may also be affected.
Remediation
