Executive Summary

The InfiniteWP Client WordPress plugin before version 1.13.6 has a vulnerability where it fails to properly verify site-connection state and request authenticity on remote-management endpoints for WordPress Multisite installations. This allows unauthenticated attackers to bind their own key, hijack an administrator session, and take over the entire network, potentially leading to remote code execution.

Detection Guidance

Check the installed version of the InfiniteWP Client plugin. If it is below 1.13.6, the system is vulnerable. Look for unauthorized key bindings or session hijacking attempts in logs.

Impact Analysis

If you use the InfiniteWP Client plugin on a WordPress Multisite installation with a version prior to 1.13.6, an attacker could hijack an administrator account, gain full control over your WordPress network, and execute arbitrary code remotely. This could lead to complete compromise of your website and data.

Compliance Impact

This vulnerability could lead to unauthorized access and data breaches, which may violate compliance requirements under GDPR, HIPAA, and other regulations. A successful exploit could expose sensitive user data, resulting in legal penalties, reputational damage, and loss of trust.

Mitigation Strategies

Update the InfiniteWP Client plugin to version 1.13.6 or later immediately. Disable the plugin if not in use. Review and audit all administrator sessions and keys for signs of compromise.
