Advisory

Source description from Wordfence Intelligence, credited to Francesco Carlucci.

The Post to CSV by BestWebSoft plugin for WordPress is vulnerable to CSV Injection in versions up to, and including, 1.3.8. This allows author-level attackers 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.
