Advisory

Source description from Wordfence Intelligence, credited to Ivan Cese.

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
