NPM IP package incorrectly identifies some private IP addresses as public
CVE-2023-42282 · GHSA-78xj-cgh5-2h22
- Affected
- npm ip >= 2.0.0, <= 2.0.0; < 1.1.9
- Fixed in
- 1.1.92.0.1· Vendor fix available
- Issue
- 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.
Recommended action: Upgrade to 2.0.1 or 1.1.9 by release line, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
