• Severity: high (CVSS 7.5 v3.1)
• Exploited in the wild: not listed in CISA KEV
• EPSS: 1.1% probability of exploitation in the next 30 days
• Public exploit or detection template: none known

• Weakness: CWE-347

Description

Forge (also called `node-forge`) is a native implementation of Transport Layer Security in JavaScript. Prior to version 1.3.0, RSA PKCS#1 v1.5 signature verification code does not check for tailing garbage bytes after decoding a `DigestInfo` ASN.1 structure. This can allow padding bytes to be removed and garbage data added to forge a signature when a low public exponent is being used. The issue has been addressed in `node-forge` version 1.3.0. There are currently no known workarounds.

Affected products

• digitalbazaar forge: before 1.3.0 — fixed in 1.3.0
• Npm Node-Forge: before 1.3.0 — fixed in 1.3.0

How to fix

Upgrade to a fixed version: digitalbazaar forge 1.3.0; Npm Node-Forge 1.3.0. Check the vendor advisory for mitigations.
