Effect Maker <= 1.2.1 - Authenticated (Subscriber+) Stored Cross-Site Scripting

Description

The Effect Maker plugin for WordPress is vulnerable to Stored Cross-Site Scripting in versions up to, and including, 1.2.1 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with subscriber-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
