CVE-2025-27400

2.9 LOW 0.3% exploit odds Fix listed XSS

What it is

Magento Long Term Support (LTS) is an unofficial, community-driven project provides an alternative to the Magento Community Edition e-commerce platform with a high level of backward compatibility. Versions prior to 20.12.3 and 20.13.0 contain a vulnerability that allows script execution in the admin panel which could lead to cross-site scripting against authenticated admin users. The attack requires an admin user with configuration access, so in practicality it is not very likely to be useful given that a user with this level of access is probably already a full admin. Versions 20.12.3 and 20.13.0 contain a patch for the issue.

Exploitability: Can be exploited from the same network segment with an admin-level account, but needs a user to act. Limited direct impact.
Exploit odds: 0.3% chance of exploitation in the next 30 days (EPSS).
Fix: A patch, advisory or fixed version is referenced. Upgrade or apply it.
