Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')

CVE-2024-41676

Medium
4.8/10

Summary

Magento-lts is a long-term support alternative to Magento Community Edition (CE). This XSS vulnerability affects the "design/header/welcome", "design/header/logo_src", "design/header/logo_src_small", and "design/header/logo_alt" system configs. They are intended to enable admins to set a text in the two cases, and to define an image URL for the other two cases. But because of previously missing escaping allowed us to input arbitrary HTML and as a consequence also arbitrary JavaScript. This issue affects versions through 20.10.0, and 21.0.0-beta1 through 21.0.0-beta2.
