(CVE-2026-9726)

Vulnerability from drupal – Published: 2026-05-27 18:32 – Updated: 2026-05-27 18:32 – Source website

Details

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.
