Attack-Flow Graph

Executive Summary

This vulnerability is a PHP Object Injection flaw in the WordPress Hygia Theme versions up to 1.21.0. It allows attackers to inject malicious objects during deserialization, potentially leading to unauthorized data manipulation or server-side code execution without authentication.

Detection Guidance

Check if the Hygia theme version 1.21.0 or earlier is installed on your WordPress site. Look for suspicious activity like unauthorized data changes or server commands. Use security plugins to scan for PHP object injection attempts.

Impact Analysis

Attackers can exploit this to manipulate site data, execute harmful actions on the server, and potentially take control of the website. Since there is no official patch, the risk remains high until mitigated.

Compliance Impact

This vulnerability allows attackers to execute harmful actions on the server without authentication, potentially leading to unauthorized data access or manipulation. Such breaches could violate GDPR by exposing personal data or HIPAA by compromising protected health information, depending on the data processed by the affected system.

Mitigation Strategies

Disable the Hygia theme if not essential. Apply Patchstack's mitigation rule if available. Contact your hosting provider or developer for assistance. Monitor for unusual activity and consider temporary removal until an official patch is released.
