Improper Verification of Cryptographic Signature in node-forge
Published 18 Mar 2022 · Updated 8 Nov 2023
Affected package
- Affected
- <1.3.0
- Fixed in
- 1.3.0
npm install node-forge@1.3.0Details
Impact
RSA PKCS#1 v1.5 signature verification code is lenient in checking the digest algorithm structure. This can allow a crafted structure that steals padding bytes and uses unchecked portion of the PKCS#1 encoded message to forge a signature when a low public exponent is being used.
Patches
The issue has been addressed in node-forge 1.3.0.

Is GHSA-cfm4-qjh2-4765 in any of your client repos?
Checking one package by hand is fine. Checking it across forty client projects is not. NPMscan reads the lockfiles in every GitHub repo you pick, finds each project with an affected node-forge, and gives you the command that fixes it.
