CVE-2025-26499

Under heavy system utilization a random race condition can occur during authentication or token refresh operation. This flaw allows one user to be granted a token intended for another user, resulting in impersonation until the session is ended. This flaw cannot be intentionally exploited due to the required concurring action by two users. However, if the event occurs a user would be inadvertently exposed to another user’s system rights and data access.

Summary		(es) Bajo una utilización intensa del sistema, puede ocurrir una condición de carrera aleatoria durante la autenticación o la operación de actualización de token. Esta falla permite que a un usuario se le conceda un token destinado a otro usuario, lo que resulta en suplantación de identidad hasta que la sesión finalice. Esta falla no puede ser explotada intencionalmente debido a la acción concurrente requerida por dos usuarios. Sin embargo, si el evento ocurre, un usuario quedaría expuesto inadvertidamente a los derechos de sistema y al acceso a datos de otro usuario.
