Use of Cryptographically Weak Pseudo-Random Number Generator (PRNG) in crypto-js - #VU141233

Vulnerability details

The vulnerability allows a remote attacker to recover security-sensitive values.

The vulnerability exists due to use of a cryptographically weak pseudo-random number generator in CryptoJS.lib.WordArray.random() when generating security-sensitive values. A remote attacker can enumerate the reduced output space to recover security-sensitive values.

An application is affected only if it uses the vulnerable function to generate security-sensitive values.
