XSS in Wpmudev Hustle – Email Marketing, Lead Generation, Optins, Popups

CVE-2026-118169

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.
