Advisory
Source description from Wordfence Intelligence.
The YaySMTP plugin for WordPress is vulnerable to Stored Cross-Site Scripting via several parameters, with at least one being the 'client_id' parameter, in versions up to, and including, 2.2.1 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, administrator and above, to inject arbitrary web scripts stored in the plugin options.
