Source description from Wordfence Intelligence, credited to Vishnupriya Ilango.
The Wise Chat plugin for WordPress is vulnerable to CSV Injection in versions up to, and including, 2.8.3. This allows unauthenticated 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.
