CVE-2019-10157
An attacker with local access could use this to construct a malicious web token setting an NBF parameter that could prevent user access indefinitely.
Does this matter?
Lower severity and a low EPSS score (0.21%). Track it; it rarely justifies an emergency change on its own.
Description
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.
