Because of this lack of validation, an attacker can supply a malicious template that the system will execute, providing remote code execution with full control over the application and its underlying environment. This vulnerability is classified as CWE\u2011829, representing untrusted code execution stemming from insecure handling of external artifacts.", "risk_and_exploitability": "The CVSS score of 9.3 signals a severe risk, indicating that an attacker that can influence the remote location of a template can run arbitrary code on the target system. Exploitation requires no authentication and no user interaction, as the system automatically fetches and executes the template during normal operation.
