The WP Discourse plugin for WordPress is vulnerable to Information Exposure in all versions up to, and including, 2.5.9.

This makes it possible for authenticated attackers, with author-level access and above, to exfiltrate sensitive Discourse API credentials to attacker-controlled servers, as well as query internal services and potentially perform further attacks.
