CVE-2026-63047Known exploitationNetwork attack vector

Unauthenticated invoice disclosure via unbound download code

Published Jul 22, 2026 · Updated Jul 22, 2026

Improper access control in JoomDonation Events Booking 5.0 through 5.8.1 allows remote attackers to download registrant invoices. The front-end invoice page chooses a PDF by a caller-controlled numeric registration ID, while checking only that a download code is present instead of binding that code to the selected registration. Invoice generation must be enabled; no authentication or user interaction is required, and exposure is limited to personal and payment data in invoices.
