CVSS 3.0
3.8 lowCVSS:3.0/AV:N/AC:L/PR:H/UI:N/S:U/C:L/I:L/A:NCVE-2019-3868
Low (3.8) in redhat keycloak. EPSS 1.0% chance of exploitation in the next 30 days. Fixed in org.keycloak:keycloak-core 6.0.0.
Keycloak up to version 6.0.0 allows the end user token (access or id token JWT) to be used as the session cookie for browser sessions for OIDC. As a result an attacker with access to service provider backend could hijack user’s browser session.
