Vulnerability from github – Published: 2026-04-28 15:30 – Updated: 2026-04-28 15:30

Details

A flaw was found in the OpenShift Container Platform build system. A user with the edit ClusterRole can inject arbitrary environment variables, such as LD_PRELOAD or http_proxy, into docker-build containers through the buildconfigs/instantiate API. This incomplete fix for a previous vulnerability allows for information disclosure, specifically impacting the confidentiality of build traffic.

Severity

4.3 (Medium)


                  
                    CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N
