Title
Keycloak-services: keycloak-services: account takeover via authentication race using reset-credentials path
Summary
A flaw was found in the authentication session handling of the keycloak-services component in Keycloak. The issue occurs because the system fails to verify if an authenticator is valid for the current authentication flow when switching between the standard authentication path and the reset credentials path. An authenticated attacker can exploit this by triggering a race condition during the credential reset process to associate their successful authentication state with another user's session. This can result in the attacker gaining full access to the victim's account and changing their password.
