Advisory
Source description from Wordfence Intelligence, credited to David Vaartjes.
The Adminer plugin for WordPress is vulnerable to authorization bypass due to a missing capability check on the adminer_load_editor() function in versions up to, and including, 1.4.5. This makes it possible for unauthenticated (no login required) attackers to access any database associated with the vulnerable WordPress server.
