CVE-2026-13007

Tenable Identity Exposure contains multiple unauthenticated API endpoints under /w/api/* that expose sensitive application configuration data including cleartext LDAP credentials, SAML configuration, user accounts, and directory settings to unauthenticated remote attackers. Affected responses are served with Cache-Control: public headers and without Vary: Cookie, allowing reverse proxies and CDNs to cache and serve sensitive data to unauthenticated users even after authentication is applied.

Summary		(es) Tenable Identity Exposure contiene múltiples endpoints de API no autenticados bajo /w/api/* que exponen datos de configuración de aplicación sensibles, incluyendo credenciales LDAP en texto claro, configuración SAML, cuentas de usuario y configuraciones de directorio, a atacantes remotos no autenticados. Las respuestas afectadas se sirven con encabezados Cache-Control: public y sin Vary: Cookie, permitiendo que los proxies inversos y las CDN almacenen en caché y sirvan datos sensibles a usuarios no autenticados incluso después de que se aplique la autenticación.
