      "value": "An issue was discovered in UiPath App Studio 21.4.4. There is a persistent XSS vulnerability in the file-upload functionality for uploading icons when attempting to create new Apps. An attacker with minimal privileges in the application can build their own App and upload a malicious file containing an XSS payload, by uploading an arbitrary file and modifying the MIME type in a subsequent HTTP request. This then allows the file to be stored and retrieved from the server by other users in the same organization."

Se presenta  una vulnerabilidad de tipo XSS persistente en la funcionalidad file-upload para subir iconos al intentar crear nuevas Apps. Un atacante con privilegios m\u00ednimos en la aplicaci\u00f3n puede crear su propia App y subir un archivo malicioso que contenga una carga \u00fatil de tipo XSS, al subir un archivo arbitrario y modificando el tipo MIME en una petici\u00f3n HTTP posterior. Esto permite entonces que el archivo sea almacenado y recuperado del servidor por otros usuarios de la misma organizaci\u00f3n"
