Element Pack Elementor Addons < 5.6.2 - Contributor+ Stored XSS

Description The plugin is vulnerable to Stored Cross-Site Scripting via the custom_attributes value in widgets due to insufficient input sanitization and output escaping on user supplied attributes. 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.
