A couple of weeks ago, we were performing a security scan for a customer using Magento shop. While auditing their website our team found a critical vulnerability in Affiliate Plus module. According to Affiliate Plus’ website, 7000+ stores use the extension. This Affiliate Plus Magento module XSS vulnerability leaves a number of Magento stores vulnerable.
