Summary

Thelia Back-office Default Twig Template before 1.1.1 contains a cross-site request forgery flaw (CWE-352) in the /admin/product/combinations/update and /admin/product/default-price/update routes. These routes accept GET requests without anti-CSRF token checks. An attacker can lure a logged-in administrator into following a crafted link that rewrites product combination prices, stock, weight, EAN and sale flags, and zeroes omitted prices. The CVSS 4.0 vector requires user interaction and grants high integrity impact.
