The Enable jQuery Migrate Helper plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the downgrade jquery version() function in all versions up to, and including, 1.4.1. This is due to the function only verifying a nonce without checking user capabilities.
