Description
WordPress Plugin Photocart Link is prone to a local file inclusion vulnerability because it fails to sufficiently verify user-supplied input. Exploiting this issue may allow an attacker to obtain sensitive information that could aid in further attacks. WordPress Plugin Photocart Link version 1.6 is vulnerable; prior versions may also be affected.
Remediation
Edit the source code to ensure that input is properly verified or disable the plugin until a fix is available
