Advisory
Source description from Wordfence Intelligence, credited to Dmitrii Ignatyev.
The Business Directory Plugin plugin for WordPress is vulnerable to CSV Injection in versions up to, and including, 6.4.3 via the class-csv-exporter.php file. This allows authenticated attackers, with author-level permissions and above, to embed untrusted input into CSV files exported by administrators, which can result in code execution when these files are downloaded and opened on a local system with a vulnerable configuration.
