How to fix?

Upgrade org.webjars.npm:node-forge to version 1.3.1 or higher.

Overview

org.webjars.npm:node-forge is a WebJar for node-forge.

Affected versions of this package are vulnerable to Improper Verification of Cryptographic Signature due to RSAs PKCS#1` v1.5 signature verification code which 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.
