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.","publishedAt":"2026-10-31T08:57:35.252Z","updatedAt":"2026-10-31T08:57:35.252Z","severity":{"score":8,"label":"High","version":"3.1","vector":"CVSS:3.1/AV:A/AC:H/PR:L/UI:N/S:C/C:H/I:H/A:H","source":"redhat"},"assigner":"redhat","products":["konflux-ci"],"affected":[{"packageName":"konflux-ci","defaultStatus":"unaffected","versions":[{"version":"0.2.2-rc.2","status":"affected","lessThan":"*","versionType":"semver"}],"collectionURL":"https://github.com/konflux-ci/konflux-ci"}],"references":["https://access.redhat.com/security/cve/CVE-2026-117681","https://bugzilla.redhat.com/show_bug.cgi?id=2563233"],"weaknesses":["CWE-295"],"ingestedAt":"2026-10-31T09:00:06.904Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/117xxx/CVE-2026-117681.json","commit":"df3e4f16bf2a907541167ff30d2baf90b6cf3e3e","baselineCommit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-117681","state":"PUBLISHED","datePublished":"2026-10-31T08:57:35.252Z","dateUpdated":"2026-10-31T08:57:35.252Z","assignerShortName":"redhat","assignerOrgId":"53f830b8-0a3f-465b-8143-3b8a9948e749","dateReserved":"2026-10-29T22:56:15.432Z"},"containers":{"cna":{"title":"Konflux-ci: ui proxy skips backend tls verification on non-openshift clusters, leaking a token that can impersonate anyone","descriptions":[{"lang":"en","value":"A flaw was found in konflux-ci.
