The available description does not specify the breadth of potential data compromise, but the mechanics could lead to unauthorized reading of local files, affecting confidentiality.", "risk_and_exploitability": "The CVSS score is 3.3 and the EPSS score is less than 1%, meaning exploitation is considered unlikely.
