CVE, Research URL

CVE-2026-84907

Published on
Sep 16, 2026
Research Description
The Eventin WordPress plugin before 4.1.24 does not properly authorise order finalisation when its offline (local) payment method is enabled, relying on a nonce that is exposed to unauthenticated visitors and never checking that the caller owns the order, allowing unauthenticated attackers to reset any existing order and its attendees to a pending state and thereby invalidate paid tickets.
Affected versions
max 4.1.24.
Status
vulnerable
