What is CVE-2025-59437?
CVE-2025-59437 is a low-severity server-side request forgery vulnerability in fedorindutny ip, published on 16 Sep 2025. It can only be exploited from the same machine or local network, with no action from the victim.
Official description
The ip (aka node-ip) package through 2.0.1 (in NPM) might allow SSRF because the IP address value 0 is improperly categorized as globally routable via isPublic. NOTE: this issue exists because of an incomplete fix for CVE-2024-29415. NOTE: in current versions of several applications, connection attempts to the IP address 0 (interpreted as 0.0.0.0) are blocked with error messages such as net::ERR_ADDRESS_INVALID. However, in some situations that depend on both application version and operating system, connection attempts to 0 and 0.0.0.0 are considered connection attempts to 127.0.0.1 (and, for this reason, a false value of isPublic would be preferable).
Weakness: CWE-918
