CVE-2024-24553: Bludit uses SHA1 as Password Hashing Algorithm

• Severity: high (CVSS 7.5 v3.1)
• Exploited in the wild: not listed in CISA KEV
• EPSS: 0.2% probability of exploitation in the next 30 days
• Public exploit or detection template: none known
• Published: 2024-06-24 · updated 2026-06-17
• Weakness: CWE-916

Description

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.

Affected products

• Bludit: from 3.14.0 through 3.15.0
