CVE-2023-7252Public exploitNetwork attack vector

Unauthenticated ticket disclosure via nonce-free download requests

Published Apr 22, 2024 · Updated Nov 22, 2024

IDOR in Tickera – Sell Tickets & Manage Events before 3.5.2.5 allows remote attackers to download other users' tickets. The ticket-download handler accepts a ticket identifier and predictable order_key without download_ticket_nonce, then fails to verify ownership. No account or user interaction is required; enumerating eight-digit order keys discloses ticket files, with no reported write or service-interruption impact.
