CVE-2024-21627
Date: January 2, 2024
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".
