CVE-2026-117681
Description
A flaw was found in konflux-ci. This vulnerability allows privilege escalation when the user interface proxy automatically disables Transport Layer Security (TLS) certificate verification for connections to internal backend services in environments lacking a default service certificate authority. Because the proxy attaches a cluster-scoped authentication token with user impersonation rights to these requests, an adjacent network attacker capable of intercepting traffic can capture the credentials to gain full administrative control of the cluster.
Statement
This vulnerability is rated as having an Important severity because successful interception allows adjacent network actors to obtain a cluster-scoped bearer token capable of arbitrary user and group impersonation, potentially resulting in full administrative compromise. In standard Red Hat OpenShift environments, the platform's service CA automatically provides trusted certificates to the proxy configuration, ensuring TLS verification remains enforced. The insecure fallback to unverified TLS connections specifically impacts deployments on non-OpenShift Kubernetes clusters where the expected service certificate authority is not present by default.
Mitigation
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability.
