NewCVE-2025-53106 (opens in a new tab)How to fix?
Upgrade org.graylog2:graylog2-server to version 6.2.4 or higher.
Overview
org.graylog2:graylog2-server is a log management platform.
Affected versions of this package are vulnerable to Improper Authorization via an incorrect permission check in the token creation process. An attacker can gain elevated privileges by crafting requests to the REST API and creating API tokens for higher-privileged users if they know the user ID.
Note: This is only exploitable if the attacker has a valid user account in the system.
Workaround
This vulnerability can be mitigated by disabling the option that allows regular users to create personal access tokens in the configuration settings under System > Configuration > Users > "Allow users to create personal access tokens"
