Input validation vulnerability in Sayfa Sayac 2.6

The Sayfa Sayac plugin for WordPress is not secure. All versions up to and including 2.6 have a vulnerability that makes it possible for an unauthenticated user to inject a harmful PHP Object into the system. This could potentially allow the attacker to delete files, retrieve sensitive data, or execute malicious code. There is no known way to exploit this vulnerability, but if other plugins or themes are installed on the system, it could give the attacker the ability to do these things.
