CVE-2026-76256
Full vulnerability record from the local CVENow database.
Description
In Splunk Enterprise versions below 10.4.2, 10.2.6, 10.0.9, and 9.4.14, and Splunk Secure Gateway versions below 3.10.9, 3.9.23, and 3.8.70, a user who does not hold the "admin" or "power" Splunk roles could read sensitive Security Assertion Markup Language setup and instance settings information through Splunk Secure Gateway Representational State Transfer (REST) API endpoints. The vulnerability is possible because the affected Security Assertion Markup Language setup and instance settings REST API endpoints do not enforce authorization requirements before returning configuration information.

La vulnerabilidad es posible porque los puntos finales de la API REST de configuración e instancia de Security Assertion Markup Language afectados no aplican requisitos de autorización antes de devolver información de configuración."
