AI Analysis
Technical Summary
The zportals WordPress plugin versions prior to 6.4.2 contain a vulnerability where one of its AJAX actions lacks proper capability and nonce verification. This flaw enables users with minimal privileges (subscriber-level) to retrieve sensitive information such as display names and email addresses of all registered users on the site, including those with administrative roles. This constitutes an information disclosure issue categorized under CWE-200.
Potential Impact

This exposure could facilitate targeted phishing or social engineering attacks but does not directly allow privilege escalation or code execution.
Mitigation Recommendations
Upgrade the zportals WordPress plugin to version 6.4.2 or later, where this vulnerability has been fixed. No other mitigation is required as the official fix addresses the issue.
