Summary
The Hustle plugin for WordPress is affected in all versions up to and including 7.8.14.3. Input in the content[cta_label] parameter is not sanitized and output is not escaped, which is a stored cross-site scripting flaw (CWE-79). An authenticated attacker with the hustle_edit_module capability can store scripts that run when a user opens an affected page. By default only Administrators hold this capability, but administrators can delegate it to lower roles such as Subscriber.

Description from the CNA
The Hustle – Email Marketing, Lead Generation, Optins, Popups plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'content[cta_label]' parameter in all versions up to, and including, 7.8.14.3 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with custom-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. By default only Administrators hold the hustle_edit_module capability, but the plugin's built-in Permissions screen allows administrators to delegate this capability to lower roles including Subscriber, enabling Subscriber-level exploitation on sites where that delegation has been configured.
