CVE-2023-6563
HIGH7.7EPSS 0.54%Allocation of Resources Without Limits in Keycloak
發布日:2023/12/14修改日:2024/2/16
描述
An unconstrained memory consumption vulnerability was discovered in Keycloak. It can be triggered in environments which have millions of offline tokens (> 500,000 users with each having at least 2 saved sessions). If an attacker creates two or more user sessions and then open the "consents" tab of the admin User Interface, the UI attempts to load a huge number of offline client sessions leading to excessive memory and CPU consumption which could potentially crash the entire system.
