Researcher Jonas Benjamin Friedli
Description

The External Login plugin for WordPress is vulnerable to sensitive information exposure in all versions up to, and including, 1.11.2 due to the 'exlog_test_connection' AJAX action lacking capability checks or nonce validation. This makes it possible for authenticated attackers, with subscriber-level access and above, to query the configured external database and retrieve truncated usernames, email addresses, and password hashes via the diagnostic test results view.
