Description

The Simple User Import Export plugin for WordPress is vulnerable to CSV Injection in all versions up to, and including, 1.1.7 via the 'Import/export users' function. This makes it possible for authenticated attackers, with Administrator-level access and above, to embed untrusted input into exported CSV files, which can result in code execution when these files are downloaded and opened on a local system with a vulnerable configuration
