## Description

The WP Abstracts plugin for WordPress is vulnerable to Sensitive Information Exposure via the wpamaillog AJAX action in all versions up to, and including, 2.7.6, due to a missing capability check and missing nonce on the wpabstracts_maillog_ajax() function. This makes it possible for authenticated attackers, with Subscriber-level access and above, to read any entry of the plugin's email log by ID, including recipient addresses, subjects and message bodies of notification and registration emails sent to other users.
