MEDIUM 6.5REMOTEWATCHLISTUPGRADEUPGRADEUPGRADE

CVE-2024-4629 is a medium-severity flaw (CVSS 6.5) affecting keycloak, build of keycloak, single sign-on. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

A vulnerability was found in Keycloak. This flaw allows attackers to bypass brute force protection by exploiting the timing of login attempts. By initiating multiple login requests simultaneously, attackers can exceed the configured limits for failed attempts before the system locks them out. This timing loophole enables attackers to make more guesses at passwords than intended, potentially compromising account security on affected systems.

Why this priority

Remotely exploitable, no login, no user action
