CVE-2026-120249
Thelia Back-office Default Twig Template before 1.1.1 CSRF via Product Combination Routes
What happened?
Thelia Back-office Default Twig Template before 1.1.1 contains a cross-site request forgery vulnerability in the /admin/product/combinations/update and /admin/product/default-price/update routes, which accept GET requests without anti-CSRF token checks. Attackers can lure a logged-in administrator into following a crafted link to rewrite product combination prices, stock, weight, EAN and sale flags, zeroing omitted prices.
