GHSA-3839-6r69-m497: Duplicate Advisory: GoUtils's randomly-generated alphanumeric strings contain significantly less entropy than expected

December 28, 2022 (updated January 23, 2026)

Duplicate Advisory

This advisory has been withdrawn because it is a duplicate of GHSA-xg2h-wx96-xgxr. This link is maintained to preserve external references.

Original Description

Randomly-generated alphanumeric strings contain significantly less entropy than expected. The RandomAlphaNumeric and CryptoRandomAlphaNumeric functions always return strings containing at least one digit from 0 to 9. This significantly reduces the amount of entropy in short strings generated by these functions.
