Overview
CVE-2026-2733 is a low-severity vulnerability. It was published on February 19, 2026 and has a CVSS 3.1 base score of 3.8 (LOW).
This vulnerability has a CVSS 3.1 base score of 3.8, rated LOW. It can be exploited remotely over the network. Some level of privileges is required for exploitation.
Technical description
A flaw was identified in the Docker v2 authentication endpoint of Keycloak, where tokens continue to be issued even after a Docker registry client has been administratively disabled. This means that turning the client “Enabled” setting to OFF does not fully prevent access. As a result, previously valid credentials can still be used to obtain authentication tokens. This weakens administrative controls and could allow unintended access to container registry resources.
Remediation
Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
