Description
WordPress Plugin WP Easy Stats is prone to a remote file include vulnerability because it fails to sufficiently sanitize user-supplied input. Exploiting this issue could allow an attacker to compromise the application and the underlying system; other attacks are also possible. WordPress Plugin WP Easy Stats version 1.8 is vulnerable; other versions may also be affected.
Remediation
Edit the source code to ensure that input is properly sanitised or disable the plugin until a fix is available
