Executive Summary

The ECS WordPress plugin before version 4.3.10 has a flaw where it does not verify if a user has permission to access custom field values from posts they do not own. This allows contributors or higher-level users to read sensitive metadata, including private or draft post details, by supplying a post identifier.

Detection Guidance

Check if the ECS WordPress plugin version is below 4.3.10. Use commands like 'wp plugin list' in WordPress CLI or inspect the plugin files in the /wp-content/plugins/ directory for version details.

Impact Analysis

If you use the ECS plugin in versions prior to 4.3.10, attackers with contributor-level access could steal private or draft post data, including custom fields and metadata. This could lead to unauthorized access to sensitive information.

Compliance Impact

This vulnerability could violate data protection regulations like GDPR or HIPAA by exposing private or sensitive data without authorization. Organizations using the vulnerable plugin may face compliance risks and potential penalties.

Mitigation Strategies

Update the ECS plugin to version 4.3.10 or later immediately. Restrict contributor-level user permissions if possible and review custom field access logs for suspicious activity.
