Affected versions of this package are vulnerable to Remote Code Execution (RCE). An attacker may bypass the Control Flow Guard (CFG). By itself, the vulnerability does not allow arbitrary code execution. However, an attacker could use the CFG in conjunction with another vulnerability, such as a remote code execution vulnerability, to run arbitrary code on a target system.
