CVE-2026-9726Network attack vector

Remote PHP code execution via unsafe deserialization

Published Jul 10, 2026 · Updated Jul 10, 2026

PHP object injection in Drupal AlternativeCommerce (Basket) before 2.1.17 allows remote attackers to execute PHP code via crafted data. The payment page passes insufficiently sanitized user-controlled payInfo data to PHP's unserialize() function. Code execution requires a viable gadget chain in the Drupal site codebase or installed dependencies; otherwise, the crafted payload only triggers object injection.
