CVE-2026-7309: Untrusted Search Path in Red Hat Red Hat OpenShift Container Platform 4
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.
AI Analysis
Technical Summary
This vulnerability involves an untrusted search path in the OpenShift Container Platform build system. Specifically, users with the 'edit' ClusterRole can inject environment variables into docker-build containers through the buildconfigs/instantiate API. This flaw allows for potential information disclosure by impacting the confidentiality of build traffic. The issue is a partial fix of a prior vulnerability and currently lacks an official remediation or patch from Red Hat.
Potential Impact
The vulnerability impacts the confidentiality of build traffic by allowing environment variable injection, which could disclose sensitive information. There is no indication of integrity or availability impact. No known exploits in the wild have been reported.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory at https://access.redhat.com/security/cve/CVE-2026-7309 for current remediation guidance. Until an official fix is released, restrict 'edit' ClusterRole permissions to trusted users only to limit potential exploitation.
