What is CVE-2025-53106?

In Graylog versions 6.2.0 to 6.2.3 and 6.3.0-alpha.1 to 6.3.0-rc.1, users can exploit a vulnerability that allows for elevated privileges through unauthorized API token creation. An attacker with access to a Graylog user account can send specifically crafted requests to the REST API, bypassing security checks and gaining unauthorized rights. This vulnerability has been addressed in versions 6.2.4 and 6.3.0-rc.2. To mitigate this risk before upgrading, it is recommended to disable the personal access token feature in the system settings.
