⚠️ Risk & Real-World Impact
Worst Case
Unauthorized users could extract sensitive post metadata including custom fields, private content, or configuration data, potentially leading to data exposure or reconnaissance for further attacks.
Likely Case
Low-privileged users or attackers who gain basic access could export post metadata they shouldn't have access to, revealing potentially sensitive information about the site's structure and content.
If Mitigated
With proper access controls and authentication checks, only authorized administrators could access the export functionality, preventing data leakage.
🎯 Exploit Status
Exploitation requires some level of access to the WordPress site but bypasses authorization checks for the export functionality.
