https://notcve.org/view.php?id=CVE-2019-10157
It was found that Keycloak's Node.js adapter before version 4.8.3 did not properly verify the web token received from the server in its backchannel logout . An attacker with local access could use this to construct a malicious web token setting an NBF parameter that could prevent user access indefinitely.

CVSS: 6.5EPSS: 0%CPEs: 2EXPL: 0CVE-2019-3875 – keycloak: missing signatures validation on CRL used to verify client certificates
https://notcve.org/view.php?id=CVE-2019-3875
A vulnerability was found in keycloak before 6.0.2. 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. Se encontró una vulnerabilidad en keycloak versión anterior a 6.0.2. • http://www.securityfocus.com/bid/108748 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2019-3875 https://access.redhat.com/security/cve/CVE-2019-3875 https://bugzilla.redhat.com/show_bug.cgi?id=1690628 • CWE-295: Improper Certificate Validation CWE-345: Insufficient Verification of Data Authenticity •
