System Dashboard < 2.8.8 - Missing Authorization to Information Disclosure (sd_constants)

Description The System Dashboard plugin for WordPress is vulnerable to unauthorized access of data due to a missing capability check on the sd_constants() function hooked via an AJAX action in all versions up to, and including, 2.8.7. This makes it possible for authenticated attackers, with subscriber-level access and above, to retrieve sensitive information such as database credentials.
