Overview
org.keycloak:keycloak-services is an open source identity and access management solution for modern applications and services.
Affected versions of this package are vulnerable to Improper Validation of Certificate with Host Mismatch when setting the verification policy to 'ALL'. This is supposed to skip hostname check but an unintended side effect is skipping trust store certificate verification. An attacker can read sensitive data from the system and perform spoofing or redirection attacks by exploiting this vulnerability.
Note:
The ANY mode should not be used in production.
