FKIE_CVE-2026-2733

Vulnerability from fkie_nvd - Published: 2026-02-19 08:16 - Updated: 2026-02-19 15:52
Severity ?
3.8 (Low) - CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:L/I:L/A:N
Summary
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.
