CVE-2026-120249 · Severity: medium · CVSS 6.5 · Published 2026-11-01

Thelia's back-office template system allows administrators to manage product combinations and pricing. An attacker can craft a malicious link that, when clicked by a logged-in admin, silently modifies product prices, stock levels, weights, and other sale flags—potentially causing inventory errors or revenue loss without the admin's knowledge.

Technical details

The vulnerability is a cross-site request forgery (CSRF) in the product combination and default price update endpoints (/admin/product/combinations/update and /admin/product/default-price/update), which accept GET requests without verifying anti-CSRF tokens. An authenticated administrator must visit a malicious link to trigger the attack; the attacker gains the ability to rewrite product attributes including prices, stock, weight, EAN codes, and sale flags.
