Name of the Vulnerable Software and Affected Versions keycloak versions prior to 3.4.2

Description A flaw was discovered that allows an attacker to misuse a client-side /etc/hosts entry to spoof a URL in a password reset request. This could lead to an attacker crafting a malicious password reset request, gaining a valid reset token, and potentially resulting in information disclosure or further attacks.
