CyberRota Analysis

AI-Generated

The vulnerability affects node-forge versions up to 1.4.0, where improper validation of nested DigestAlgorithm sequences during RSA PKCS#1 v1.5 signature verification allows attackers to inject arbitrary data, potentially forging valid signatures with low-exponent RSA keys. This could lead to unauthorized access or manipulation of data, making it critical for developers and organizations using node-forge to prioritize patching this issue to maintain the integrity of their cryptographic operations.

Original NVD Description

node-forge through 1.4.0 fails to validate element count in nested DigestAlgorithm sequences during RSA PKCS#1 v1.5 signature verification. Attackers can embed garbage bytes inside the DigestAlgorithm sequence to forge valid signatures for arbitrary messages using low-exponent RSA keys. This is an incomplete fix for CVE-2026-33894.
