Description

DataEase is an open source data visualization and analysis tool. Prior to version 1.18.11, DataEase has a vulnerability that allows an attacker to to obtain user cookies. The program only uses the `ImageIO.read()` method to determine whether the file is an image file or not. There is no whitelisting restriction on file suffixes.
