Technical description
The Smart Slider 3 plugin for WordPress is vulnerable to Directory Traversal in all versions up to, and including, 3.5.1.36 via the replaceHTMLImage function. This makes it possible for authenticated attackers, with administrator-level access and above, to read the contents of arbitrary files on the server, which can contain sensitive information.
