Smart Slider 3 <= 3.5.1.33 - Authenticated (Subscriber+) Arbitrary File Read via actionExportAll

The Smart Slider 3 plugin for WordPress is vulnerable to Arbitrary File Read in all versions up to, and including, 3.5.1.33 via the 'actionExportAll' function. This makes it possible for authenticated attackers, with Subscriber-level access and above, to read the contents of arbitrary files on the server, which can contain sensitive information.
