Description
WordPress Plugin Shopping Cart & eCommerce Store is prone to a vulnerability that lets attackers upload arbitrary files because the application fails to properly sanitize user-supplied input. An attacker can exploit this vulnerability to upload arbitrary code and run it in the context of the webserver process. This may facilitate unauthorized access or privilege escalation; other attacks are also possible. WordPress Plugin Shopping Cart & eCommerce Store version 3.0.8 is vulnerable; prior versions may also be affected.
Remediation
Update to plugin version 3.0.9 or latest
