    Affected versions of this package are vulnerable to Server-side Request Forgery (SSRF) via the isLocalhost() function which misclassifies IP addresses and allows localhost checks to be bypassed. An attacker can access internal network resources by using alternative representations such as IPv6-mapped IPv4 addresses (e.g.,::ffff:127.0.0.1), allowing restricted localhost access to be incorrectly permitted.
