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.","epss":null,"exploits":[],"kev":null,"metrics":[{"score":7.2,"severity":"high","source":"CNA: redhat","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},{"score":7.2,"severity":"high","source":"NVD: secalert@redhat.com","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H","version":"3.1"}],"modifiedAt":1794439030750,"publishedAt":1794436512202,"references":[{"source":"CNA: redhat","tags":["vdb-entry","x_refsource_REDHAT"],"url":"https://access.redhat.com/security/cve/CVE-2026-125637"},{"source":"CNA: redhat","tags":["issue-tracking","x_refsource_REDHAT"],"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2569294"},{"source":"secalert@redhat.com","tags":[],"url":"https://access.redhat.com/security/cve/CVE-2026-125637"},{"source":"secalert@redhat.com","tags":[],"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2569294"}],"remediation":[{"kind":"workaround","source":"CNA: redhat","text":"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."}],"revision":"4a7c9054c0baa456a1510bb354c22a94caa4ee737c5e40cfcac45534881e4593","sources":[{"modifiedAt":1794436512202,"name":"CNA: redhat","retrievedAt":1794438504984,"url":"https://www.cve.org/CVERecord?id=CVE-2026-125637"},{"modifiedAt":1794439030750,"name":"NVD","retrievedAt":1794443578708,"url":"https://nvd.nist.gov/vuln/detail/CVE-2026-125637"}],"ssvc":null,"status":"published","title":"Konflux-ci: unvalidated hostname fields enable caddyfile config injection in the konflux ui proxy generator, allowing an unauthenticated route to be spliced ahead of the forward_auth/impersonate authorization chain","updatedAt":1794443578708}
