CVE-2024-0436: Prevent timing attack for single-user password check

• Severity: medium (CVSS 5.9 v3.1)
• Exploited in the wild: not listed in CISA KEV
• EPSS: 0.5% probability of exploitation in the next 30 days
• Public exploit or detection template: none known
• Published: 2024-02-26 · updated 2026-06-17
• Weakness: CWE-203

Description

Theoretically, it would be possible for an attacker to brute-force the password for an instance in single-user password protection mode via a timing attack given the linear nature of the `!==` used for comparison. The risk is minified by the additional overhead of the request, which varies in a non-constant nature making the attack less reliable to execute
