Hostname values defined in the KonfluxUI custom resource are inserted directly into proxy configuration files without adequate validation or sanitization. An authenticated user with permissions to modify the custom resource can inject malicious configuration directives to bypass authentication and authorization controls, potentially exposing internal backend services. In addition, providing malformed input can cause the configuration generator to fail, resulting in a denial of service (DoS) by preventing the proxy from starting."], "mitigation": {"lang": "en:us", "value": "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."}, "name": "CVE-2026-125637", "public_date": "2026-11-10T00:00:00Z", "references": ["https://www.cve.org/CVERecord?id=CVE-2026-125637\nhttps://nvd.nist.gov/vuln/detail/CVE-2026-125637"], "statement": "Red Hat Product Security rates this vulnerability as Critical because successful exploitation completely circumvents the proxy's authentication and impersonation enforcement, granting unauthenticated access to internal backend services and the Kubernetes API. While triggering the vulnerability requires administrative privileges to modify the KonfluxUI custom resource or manage GitOps manifests, the resulting compromise undermines the primary security boundary the proxy was designed to establish.", "threat_severity": "Important"}
