Element Pack Elementor Addons < 5.5.4 - Contributor+ Stored XSS via Trailer Box Widget

Description The plugin is vulnerable to Stored Cross-Site Scripting via the ‘element_pack_wrapper_link’ attribute of the Trailer Box widget 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.
