CVE-2026-30972

Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. Prior o 9.5.2-alpha.10 and 8.6.23, Parse Server's rate limiting middleware is applied at the Express middleware layer, but the batch request endpoint (/batch) processes sub-requests internally by routing them directly through the Promise router, bypassing Express middleware including rate limiting. An attacker can bundle multiple requests targeting a rate-limited endpoint into a single batch request to circumvent the configured rate limit. Any Parse Server deployment that relies on the built-in rate limiting feature is affected. This vulnerability is fixed in 9.5.2-alpha.10 and 8.6.23.

Summary		(es) Parse Server es un backend de código abierto que puede ser desplegado en cualquier infraestructura que pueda ejecutar Node.js. Antes de 9.5.2-alpha.10 y 8.6.23, el middleware de limitación de tasa de Parse Server se aplica en la capa de middleware de Express, pero el endpoint de solicitudes por lotes (/batch) procesa sub-solicitudes internamente enrutándolas directamente a través del router Promise, eludiendo el middleware de Express, incluida la limitación de tasa. Un atacante puede agrupar múltiples solicitudes dirigidas a un endpoint con limitación de tasa en una única solicitud por lotes para eludir el límite de tasa configurado. Cualquier despliegue de Parse Server que dependa de la función de limitación de tasa incorporada se ve afectado. Esta vulnerabilidad está corregida en 9.5.2-alpha.10 y 8.6.23.
