The Basket module enables e-commerce and checkout functionality for Drupal sites.
The module does not sufficiently sanitize user-supplied data before passing it to PHP's unserialize().
An attacker can supply a crafted payload and trigger PHP Object Injection. If a viable gadget chain exists in the site codebase or installed dependencies, this can result in arbitrary PHP code execution.
