May 24, 2022 (updated July 17, 2023)

A file upload restriction bypass exists in Magento 2.1 prior to 2.1.18, Magento 2.2 prior to 2.2.9, Magento 2.3 prior to 2.3.2. An authenticated user with administrator privileges to the import feature can make modifications to a configuration file, resulting in potentially unauthorized removal of file upload restrictions.
