CVE-2026-76265

Estado: AnalizadaMedia (6.5)—

En las versiones de Splunk Enterprise anteriores a 10.4.3, 10.2.7, 10.0.10 y 9.4.15, y en las versiones de Splunk Secure Gateway anteriores a 3.10.11, 3.9.25 y 3.8.72, un usuario que no tenga los roles de Splunk "admin" o "power" podría acceder a funcionalidades privilegiadas de Splunk Secure Gateway. Con este acceso, el usuario podría hacer que Splunk Secure Gateway firme cargas útiles controladas por el atacante. La vulnerabilidad es posible porque varios endpoints de la API de Representational State Transfer (REST) de Splunk Secure Gateway no aplican los requisitos de autorización antes de procesar las solicitudes.
