Keycloak: potential bypass of brute force protection

Description

A vulnerability was found in Keycloak. This flaw allows attackers to bypass brute force protection by exploiting the timing of login attempts.

This timing loophole enables attackers to make more guesses at passwords than intended, potentially compromising account security on affected systems.

Remediation

Workaround:

  • Mitigation for this issue is either not available or the currently available options don't meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
