The Pack Elementor addon < 2.1.5 - Authenticated (Contributor+) Stored Cross-Site Scripting

Description

The The Pack Elementor addon plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘slider_options’ parameter in all versions up to, and including, 2.1.4 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
