What the vulnerability does
01Description
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.

External Login versions up to 1.11.2 expose sensitive information to authenticated users. A logged-in attacker can read data they should not have access to through the application's information disclosure vulnerability.
