Name of the Vulnerable Software and Affected Versions mcp-server-siri-shortcuts (affected versions not specified)

Description This issue allows local attackers to escalate privileges on affected systems. An attacker must first have the ability to execute low-privileged code on the target system. The flaw is due to insufficient validation of user-supplied input within the shortcutName parameter before it is used to execute a system call. This can be leveraged to execute arbitrary code in the context of the service account.
