Server-side Request Forgery (SSRF)

private-ip is a Check if IP address is private.

Affected versions of this package are vulnerable to Server-side Request Forgery (SSRF). An attacker can perform a large range of requests to ARIN reserved IP ranges, resulting in an indeterminable number of critical attack vectors, allowing remote attackers to request server-side resources or potentially execute arbitrary code through various SSRF techniques.

Note: previous fix (2.2.0) was incomplete because it didn't take into account different representations of IPs. A complete fixed commit was released in 2.3.0

How to fix Server-side Request Forgery (SSRF)?

Upgrade private-ip to version 2.3.0 or higher.
