                Description:
                A vulnerability has been identified in PHPWCMS, which could be 
exploited to conduct cross-site request forgery attacks.
                This issue is caused due to input validation errors in the 
administrative interface when processing HTTP requests, 
                which could be exploited by attackers to manipulate certain 
data by tricking an administrator into visiting a malicious web page.
