Description
WordPress Plugin FireStats is prone to a remote file include vulnerability because it fails to sufficiently sanitize user-supplied data. Exploiting this issue may allow an attacker to compromise the application and the underlying system; other attacks are also possible. WordPress Plugin FireStats version 1.6.1 is vulnerable; prior versions may also be affected.
Remediation
Update to plugin version 1.6.2 or latest
