      "value": "SAPUI5 allows a key user with content adaptation privileges to inject malicious script content into persisted application changes. When another user subsequently opens the adapted application, the injected script executes in the victim's browser session. Successful exploitation could allow the attacker to access sensitive session data and perform unauthorized actions on behalf of the victim, resulting in a high impact on confidentiality and integrity. There is no impact on availability."

      "value": "SAPUI5 permite a un usuario clave con privilegios de adaptación de contenido inyectar contenido de script malicioso en cambios de aplicación persistidos. Cuando otro usuario abre posteriormente la aplicación adaptada, el script inyectado se ejecuta en la sesión del navegador de la víctima. La explotación exitosa podría permitir al atacante acceder a datos sensibles de la sesión y realizar acciones no autorizadas en nombre de la víctima, lo que resultaría en un alto impacto en la confidencialidad e integridad. No hay impacto en la disponibilidad."
