Advisory
Source description from Wordfence Intelligence, credited to Kévin Mosbahi (Mika).
The Emails & Newsletters with Jackmail plugin for WordPress is vulnerable to CSV Injection in versions up to, and including, 1.2.22. This allows authenticated attackers, with subscriber-level permissions 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.
