NPM IP package incorrectly identifies some private IP addresses as public
The isPublic()
function in the NPM package ip
doesn't correctly identify certain private IP addresses in uncommon formats such as 0x7F.1
as private. Instead, it reports them as public by returning true
. This can lead to security issues such as Server-Side Request Forgery (SSRF) if isPublic()
is used to protect sensitive code paths when passed user input. Versions 1.1.9 and 2.0.1 fix the issue.
ip SSRF improper categorization in isPublic
The ip package through 2.0.1 for Node.js might allow SSRF because some IP addresses (such as 127.1, 01200034567, 012.1.2.3, 000:0:0000::01, and ::fFFf:127.0.0.1) are improperly categorized as globally routable via isPublic. NOTE: this issue exists because of an incomplete fix for CVE-2023-42282.
