Advisory
Source description from Wordfence Intelligence, credited to ed32.dll.
The Simple History plugin for WordPress is vulnerable to CSV Injection in versions up to, and including, 3.3.1. This allows subscriber-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.
