Hustle Plugin for WordPress Allows Unapproved Data Changes

CVE-2026-2263 · published 7 months ago
Summary

The Hustle plugin for WordPress, used for email marketing and lead generation, is missing a security check that could let hackers manipulate marketing data. This means they could fake conversion tracking for any email campaign, even if it's not visible to users. To fix this, update the plugin to the latest version or remove it if you're not using it to prevent potential data tampering.

The Hustle – Email Marketing, Lead Generation, Optins, Popups plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the 'hustle_module_converted' AJAX action in all versions up to, and including, 7.8.10.2. This makes it possible for unauthenticated attackers to forge conversion tracking events for any Hustle module, including draft modules that are never displayed to users, thereby manipulating marketing analytics and conversion statistics.
