FKIE_CVE-2025-11271

Vulnerability from fkie_nvd - Published: 2025-11-06 05:15 - Updated: 2026-10-07 21:10
Severity
5.3 (Medium) - CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N
Summary
The Easy Digital Downloads plugin for WordPress is vulnerable to Order Manipulation in all versions up to, and including, 3.5.2 due to an order verification bypass. The verification is unconditionally skipped when the POST body includes verification_override=1. Because this value is attacker-supplied, an unauthenticated actor can submit a forged IPN and have it treated as verified, even on production sites and with verification otherwise enabled. A valid PayPal transaction id is needed, restricting order manipulation to orders placed by the attacker. This, in turn, requires them to have a customer account.

La verificaci\u00f3n se omite incondicionalmente cuando el cuerpo de la solicitud POST incluye verification_override=1.

Se necesita un ID de transacci\u00f3n de PayPal v\u00e1lido, lo que restringe la manipulaci\u00f3n de pedidos a los pedidos realizados por el atacante. Esto, a su vez, les exige tener una cuenta de cliente."
