Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Keycloak Services (Maven org.keycloak:keycloak-services) versions before 22.0.12, from 23.0.0 before 24.0.7, and from 25.0.0 before 25.0.4 are affected. An attacker who can send many login attempts in parallel can make more password guesses than the brute force protection settings allow, because the lockout check runs before the user is locked. Upgrade to 22.0.12, 24.0.7, 25.0.4, or a later fixed release.
