{"id":"CVE-2026-23904","summary":"Apache Kyuubi: Unrestricted access via Kyuubi engine-ui proxy","details":"Kyuubi Engine UI proxy accepts a host and port from the request path and proxies HTTP requests to that destination. A remote requester with network access to the proxy can cause the Kyuubi server to send HTTP requests to arbitrary reachable hosts, resulting in SSRF or open-proxy behavior.\n\n\nThis issue affects Apache Kyuubi: from 1.8.0 before 1.12.0.\n\nUsers are recommended to upgrade to version 1.12.0, which disables the proxy by default. To restore proxied Engine UI, set kyuubi.frontend.rest.engine.ui.proxy.enabled=true and configure allowed target hosts with kyuubi.frontend.rest.engine.ui.proxy.hosts.","modified":"2026-08-04T11:50:29.973866451Z","published":"2026-07-29T09:07:18.168Z","database_specific":{"cna_assigner":"apache","cwe_ids":["CWE-923"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/23xxx/CVE-2026-23904.json"},"references":[{"type":"WEB","url":"http://www.openwall.com/lists/oss-security/2026/07/29/3"},{"type":"WEB","url":"https://repo.maven.apache.org/maven2"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/23xxx/CVE-2026-23904.json"},{"type":"ADVISORY","url":"https://lists.apache.org/thread/ps79fcfx49ox9kwgztc5t5bw0tyhck9m"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-23904"},{"type":"FIX","url":"https://github.com/apache/kyuubi/pull/7483"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/apache/kyuubi","events":[{"introduced":"aaef532491f75891e00b30ce77ddd35145ced4b3"},{"fixed":"bca17a7b5cfa0d32440832f5611f922164644943"}],"database_specific":{"source":"AFFECTED_FIELD","extracted_events":[{"introduced":"1.8.0"},{"fixed":"1.12.0"}]}}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-23904.json"}}],"schema_version":"1.8.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L"}]}
