USN-8452-1: pbkdf2 vulnerability

Publication date

18 June 2026

Overview

pbkdf2 could be made to generate predictable cryptographic keys if it received specially crafted input.


Packages

  • node-pbkdf2 - PBKDF2 with any supported hashing algorithm in Node

Details

Nikita Skovoroda discovered that pbkdf2 did not properly validate
certain algorithm names. An attacker could possibly use this issue to
generate predictable cryptographic keys, resulting in signature spoofing.
