Summary
The YaySMTP WordPress plugin, up to and including version 2.7.8, contains a SQL injection flaw in its search parameter that lets an attacker with administrator-level access or higher read sensitive data from the site's database. The attack is carried out over the network, but only by a logged-in administrator, and no user interaction is needed.

Read the original description
The YaySMTP – WP Mail SMTP with Email Logs, Tracking & Reports plugin for WordPress is vulnerable to time-based SQL Injection via the 'params[searchKey]' parameter in all versions up to, and including, 2.7.8 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with administrator-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.
