SB2026080726 - Use of Cryptographically Weak Pseudo-Random Number Generator (PRNG) in crypto-js

Description

This security bulletin contains information about 1 vulnerability.

1) Use of Cryptographically Weak Pseudo-Random Number Generator (PRNG) (CVE-ID: N/A)

CWE-ID: CWE-338 - Use of Cryptographically Weak Pseudo-Random Number Generator (PRNG)

CVSSv4: 9.2 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N]

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.

Remediation
