Advisory
Source description from Wordfence Intelligence, credited to R3N0.
The Smart Slider 3 plugin for WordPress is vulnerable to Stored Cross-Site Scripting in versions up to, and including, 3.5.1.9 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with contributor-level permissions and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
