CVE-2026-64821
djangoSIGE 1.10 CSRF via GET-based Order Cancellation Views
Description
djangoSIGE through 1.10 (commit a6fe7e8) contains a cross-site request forgery vulnerability that allows unauthenticated attackers to cancel sales or purchase orders on behalf of authenticated users by exploiting order-cancellation logic implemented inside HTTP GET method handlers in CancelarOrcamentoVendaView, CancelarPedidoVendaView, CancelarOrcamentoCompraView, and CancelarPedidoCompraView. Attackers can lure an authenticated victim with change_orcamentovenda or equivalent permissions to a page containing a cross-origin reference such as an img tag pointing to the cancellation endpoint, bypassing CSRF token validation entirely since Django's CsrfViewMiddleware only enforces CSRF checks on unsafe HTTP methods.

Action Type Old Value New Value Added Translation Title: djangoSIGE de thiagopena, Description: djangoSIGE a través de 1.10 (commit a6fe7e8) contiene una vulnerabilidad de falsificación de petición en sitios cruzados que permite a atacantes no autenticados cancelar órdenes de venta o compra en nombre de usuarios autenticados, explotando la lógica de cancelación de órdenes implementada dentro de los manejadores del método HTTP GET en CancelarOrcamentoVendaView, CancelarPedidoVendaView, CancelarOrcamentoCompraView y CancelarPedidoCompraView. Los atacantes pueden atraer a una víctima autenticada con permisos de change_orcamentovenda o equivalentes a una página que contenga una referencia de origen cruzado, como una etiqueta img que apunte al punto final de cancelación, eludiendo completamente la validación del token CSRF ya que el CsrfViewMiddleware de Django solo aplica las comprobaciones CSRF en métodos HTTP inseguros. -
