CVE-2026-33241

Salvo is a Rust web framework. Prior to version 0.89.3, Salvo's form data parsing implementations (`form_data()` method and `Extractible` macro) do not enforce payload size limits before reading request bodies into memory. This allows attackers to cause Out-of-Memory (OOM) conditions by sending extremely large payloads, leading to service crashes and denial of service. Version 0.89.3 contains a patch.

Summary		(es) Salvo es un framework web de Rust. Antes de la versión 0.89.3, las implementaciones de análisis de datos de formulario de Salvo ('form_data()' método y 'Extractible' macro) no aplican límites de tamaño de carga útil antes de leer los cuerpos de las solicitudes en la memoria. Esto permite a los atacantes causar condiciones de falta de memoria (OOM) enviando cargas útiles extremadamente grandes, lo que lleva a caídas del servicio y denegación de servicio. La versión 0.89.3 contiene un parche.
