In the module "Pixel Plus: Events + CAPI + Pixel Catalog for Facebook Module" (facebookconversiontrackingplus) up to version 2.4.9 from Smart Modules for PrestaShop, a guest can download personal information without restriction. Due to a lack of permissions control, a guest can access exports from the module which can lead to a leak of personal information from ps_customer table such as name / surname / email.
