Executive Summary

The RTMKit WordPress plugin before version 2.0.9 has a vulnerability where an AJAX action does not check user capabilities. This allows users with at least the Contributor role to read titles of other users' private, draft, pending, scheduled, or trashed posts by directly accessing post identifiers. It is an Insecure Direct Object Reference (IDOR) issue.

Detection Guidance

To detect this vulnerability, check if the RTMKit WordPress plugin version is below 2.0.9. You can use commands like 'wp plugin list' in WordPress CLI or inspect the plugin files for version details. Test by attempting to access private post titles as a Contributor role user via crafted AJAX requests.

Impact Analysis

Attackers with Contributor-level access can view sensitive post titles they should not see. This includes private drafts or posts in other non-published states. It may also allow enumeration of user accounts via login or nicename.

Compliance Impact

This vulnerability could lead to unauthorized access to private content, potentially violating data protection requirements under GDPR or HIPAA if sensitive information is exposed. Organizations may face compliance risks if user data is compromised.

Mitigation Strategies

Immediately update the RTMKit WordPress plugin to version 2.0.9 or later. If updating is not possible, consider disabling the plugin temporarily until a patch is applied. Review user roles and permissions to ensure Contributors do not have unnecessary access to sensitive post data.
