Technical details

The Ninja Forms - Excel Export plugin for WordPress is vulnerable to an Insecure Direct Object Reference (IDOR) via the 'spreadsheet_export_form_id' parameter in versions up to and including 3.3.6. The vulnerability stems from a lack of proper validation and authorization checks on the user-controlled form ID key. An authenticated attacker with subscriber-level permissions or higher can iterate through form IDs to generate and download XLSX files containing all submission data for any form on the site. This data typically includes personally identifiable information (PII) such as names, emails, and addresses. The issue is tracked as CWE-639.
