Design/Logic Flaw

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 availab...

Code injection

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...

CVE-2019-3875

Keycloak prior to 6.0.2 is affected by CVE-2019-3875 due to missing signatures validation on CRLs used for client-certificate verification. This can enable MITM-style attacks via CRLs obtained over untrusted networks (CDP/HTTP/LDAP). Red Hat’s advisory RHSA-2020:2366 flags this as a security fix,...
