CVE-2024-21627 Information

Description

PrestaShop is an open-source e-commerce platform. Prior to versions 8.1.3 and 1.7.8.11 some event attributes are not detected by the isCleanHTML method. Some modules using the isCleanHTML method could be vulnerable to cross-site scripting. Versions 8.1.3 and 1.7.8.11 contain a patch for this issue. The best workaround is to use the HTMLPurifier library to sanitize html input coming from users. The library is already available as a dependency in the PrestaShop project. Beware though that in legacy object models fields of HTML type will call isCleanHTML.
