CVE-2026-26061

Fleet is open source device management software. Prior to 4.81.0, Fleet contained multiple unauthenticated HTTP endpoints that read request bodies without enforcing a size limit. An unauthenticated attacker could exploit this behavior by sending large or repeated HTTP payloads, causing excessive memory allocation and resulting in a denial-of-service (DoS) condition. Version 4.81.0 patches the issue.

Summary		(es) Fleet es un software de gestión de dispositivos de código abierto. Antes de 4.81.0, Fleet contenía múltiples puntos finales HTTP no autenticados que leían cuerpos de solicitud sin aplicar un límite de tamaño. Un atacante no autenticado podría explotar este comportamiento enviando cargas útiles HTTP grandes o repetidas, causando una asignación excesiva de memoria y resultando en una condición de denegación de servicio (DoS). La versión 4.81.0 soluciona el problema.
