An attacker who can supply a malicious catalog can include a shell(<command>) expression that will run when the catalog source is accessed, resulting in arbitrary code execution on the host. The weakness aligns with command injection and dynamic code execution, as enumerated by the associated CWEs.", "risk_and_exploitability": "The CVSS score of 8.8 marks the issue as high severity, indicating significant potential impact.
