Overview
org.keycloak:keycloak-server-spi-private is an open source identity and access management solution for modern applications and services.
Affected versions of this package are vulnerable to Man-in-the-Middle (MitM). The X.509 authenticator supports the verification of client certificates through the CRL, where the CRL list can be obtained from the URL provided in the certificate itself (CDP) or through the separately configured path. The CRL are often available over the network through unsecured protocols (http or ldap) and hence the caller should verify the signature and possibly the certification path. Keycloak currently doesn't validate signatures on CRL, which can result in a possibility of various attacks like man-in-the-middle.
