CVE-2026-3646 enituretechnology CVE debrief

Who should care

Users of the LTL Freight Quotes – R+L Carriers Edition plugin for WordPress should be aware of this vulnerability, as it allows unauthenticated attackers to modify the plugin's subscription plan settings. Affected operators, platform administrators, vulnerability management teams, and security teams should review their current subscription plans and monitor for unauthorized changes.

Technical summary

The vulnerability exists 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. The CVSS score of 5.3 indicates a medium severity vulnerability.

Defensive priority

Medium priority given the CVSS score of 5.3 and the potential impact on subscription plan settings. Implement additional security measures to prevent unauthorized access to WordPress options and monitor subscription plan settings for unauthorized changes. Consider compensating controls for exposed systems while remediation is scheduled and verified. Review relevant monitoring, detection, and logs for exposed assets that need extra review. Track exceptions, retest remediated assets, and close the item only after evidence is documented. Update the LTL Freight Quotes – R+L Carriers Edition plugin to a version that includes a fix for this vulnerability. Perform an asset inventory to identify potentially affected systems. Implement rollback/change windows for updates. Track source references for additional information.
