Technical details

The Fluent Forms plugin for WordPress is vulnerable to an Insecure Direct Object Reference (IDOR) in versions up to and including 6.2.8. The vulnerability exists within the 'transaction' parameter due to missing validation on a user-controlled key. Because submission IDs, form IDs, and transaction timestamps are predictable or observable, unauthenticated attackers can brute-force valid transaction hashes. Successful exploitation allows the retrieval of sensitive payment data, including customer PII and order details. The issue is addressed in version 6.2.9.
