description

Printcart Store – Web to Print Product Designer for WooCommerce versions through 2.13.2 can allow unauthenticated users to place attacker-controlled files outside the intended upload location, potentially resulting in server-side code execution. Exposure requires the Advanced Upload Popup setting to be enabled.

mitigation

Disable the Advanced Upload Popup setting and restrict or disable the plugin until an updated release is available. No fixed version is recorded in the advisory.
