CVE-2026-45776

Estado: AnalizadaMedia (5.3)—

OpenXDMoD is an open framework for collecting and analyzing HPC metrics. Prior to version 11.0.3, a flaw in Open XDMoD's access control logic allows an attacker to submit a crafted HTTPS POST request that sets a session variable used for authorization decisions. If an installation of Open XDMoD includes the optional Job Performance (SUPReMM) module, an attacker could bypass intended data access restrictions and view other users' compute job efficiency metrics. All deployments of Open XDMoD prior to version 11.0.3 that contain the optional Job Performance (SUPReMM) module are impacted.

Antes de la versión 11.0.3, una falla en la lógica de control de acceso de Open XDMoD permite a un atacante enviar una solicitud POST HTTPS manipulada que establece una variable de sesión utilizada para decisiones de autorización. Si una instalación de Open XDMoD incluye el módulo opcional Job Performance (SUPReMM), un atacante podría eludir las restricciones de acceso a datos previstas y ver las métricas de eficiencia de trabajos de cómputo de otros usuarios. Todas las implementaciones de Open XDMoD anteriores a la versión 11.0.3 que contienen el módulo opcional Job Performance (SUPReMM) están afectadas. Este problema fue reportado de forma privada el 06-04-2026, y en este momento no hay evidencia de que esta vulnerabilidad haya sido explotada en la naturaleza.
