GHSA-CXM3-2C37-CC6H

Vulnerability from github – Published: 2024-06-24 09:30 – Updated: 2024-06-24 09:30

Details

Bludit uses the SHA-1 hashing algorithm to compute password hashes. Thus, attackers could determine cleartext passwords with brute-force attacks due to the inherent speed of SHA-1. In addition, the salt that is computed by Bludit is generated with a non-cryptographically secure function.
