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 WordPress components

  • Eventin – Event Calendar, Tickets, Registration, Booking & WooCommerce Plugin · wp-event-solution
    Confirmed match Active
    From 4.1.5 (including) to 4.1.24 (excluding)
    View on WordPress.org

A confirmed match is backed by the plugin or theme slug. A possible match is based on the product name only and should be verified.

Affected products and versions

  • Unknown Eventin — From 4.1.5 (including) to 4.1.24 (excluding)
