Missing Authorization vulnerability in Rustaurius Ultimate WP Mail allows Exploiting Incorrectly Configured Access Control Security Levels. This issue affects Ultimate WP Mail: from n/a through 1.3.5.
AnalysisAI
Authenticated low-privileged users can exploit a missing authorization check in Ultimate WP Mail plugin for WordPress up to version 1.3.5 to bypass access controls, potentially leading to full site takeover.
Technical ContextAI
Ultimate WP Mail is a WordPress plugin that provides email management features. The CWE-862 (Missing Authorization) vulnerability indicates that certain plugin actions or endpoints lack proper capability checks, allowing users with minimal roles (e.g., Subscriber) to perform administrative operations. This typically occurs when AJAX or REST endpoints are registered without sufficient permission callbacks, enabling unauthorized access to sensitive functionality.
RemediationAI
Update the Ultimate WP Mail plugin to version 1.3.6 or later as soon as the fix is released. Until a patch is available, disable the plugin on production sites. If disabling is not an option, restrict administrative access to trusted users and monitor for anomalous activity; however, this only partially mitigates the risk because the vulnerability may be accessible via authenticated REST API calls.
