Description
Joomla Extension - j2commerce.com - Any order can be marked Failed by anyone in J2Store 1.0.0-3.3.2, 4.0.0-4.0.22, 4.1.0-4.1.7 - Unauthenticated denial-of-service against the order pipeline: mass-failing pending orders to disrupt revenue and force manual reprocessing, or flipping already-fulfilled orders back to `FAILED` to cause operational confusion (unwarranted refunds/cancellations, customer-support load). Unlike the earlier confirmation-fraud issue, this required no correct payment amount or transaction data at all.
