Element Pack Addons for Elementor vulnerabilities

The Element Pack Addons for Elementor plugin for WordPress is vulnerable to Email Header Injection in all versions up to, and including, 8.3.15 via the `element_pack_contact_form` AJAX action. This is due to insufficient sanitization of newline characters in user-supplied input that gets concatenated into email headers. This makes it possible for unauthenticated attackers to inject arbitrary email headers into emails sent by the contact form.

The Element Pack Addons for Elementor plugin for WordPress (up to version 8.4.2) is vulnerable to Stored Cross-Site Scripting via the SVG Image Widget. The render_svg() function fetches SVG content from remote URLs without proper sanitization, allowing authenticated attackers (Contributor level and above) to inject arbitrary JavaScript in SVG files.

The Element Pack Addons for Elementor plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the Open Street Map widget's marker content parameter in all versions up to, and including, 8.3.4. This is due to insufficient input sanitization and output escaping on user-supplied attributes in the render function. 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.
