Auth bypass in Enituretechnology Ltl Freight Quotes – R+l Carriers Edition

CVE-2026-3646

The LTL Freight Quotes – R+L Carriers Edition plugin for WordPress is vulnerable to Missing Authorization via the plugin's webhook handler in all versions up to, and including, 3.3.13. This is due to missing authentication, authorization, and nonce verification on a standalone PHP file that directly processes GET parameters and updates WordPress options. This makes it possible for unauthenticated attackers to modify the plugin's subscription plan settings, effectively downgrading the store from a paid plan to the Trial Plan, changing the store type, and manipulating subscription expiration dates, potentially disabling premium features such as Dropship and Hazardous Material handling.
