An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-23904 in the wild and no public exploit code.\n\nAffected product: Apache Kyuubi. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-23904/ (Markdown: https://insights.sbomify.com/CVE-2026-23904/index.md)","id":"CVE-2026-23904","markdown":"https://insights.sbomify.com/CVE-2026-23904/index.md","name":"CVE-2026-23904","record":{"aliases":["GHSA-qvj4-xxw2-22gf"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["data_read","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Apache Kyuubi","requires_auth":"none","summary":"Remote attackers can exploit the Kyuubi Engine UI proxy to send HTTP requests to arbitrary hosts, enabling Server-Side Request Forgery attacks.","user_interaction":"not_required","vuln_class":"ssrf"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"apache","cpe":[{"product":"kyuubi","vendor":"apache"}],"cvss":{"score":7.3,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L","version":"3.1"},"cwes":[{"id":"CWE-923","name":"Improper Restriction of Communication Channel to Intended Endpoints"}],"description":"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\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.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"Apache Kyuubi: Unrestricted access via Kyuubi engine-ui proxy","id":"CVE-2026-23904","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"ssrf","year":"2026"},"n_packages":0,"n_references":2,"next":{"headline":"Apache Druid: Authentication Bypass via LDAP Anonymous Bind","id":"CVE-2026-23906"},"packages":[],"prev":{"headline":"Apache Shiro: Auth bypass when accessing static files only on case-insensitive filesystems","id":"CVE-2026-23903"},"products":["Apache Kyuubi"],"published":"2026-07-29","related":[{"cvss_score":9.8,"headline":"Apache Kyuubi: REST batch multipart upload path traversal allows controlled file write","id":"CVE-2026-52680","kev_date_added":null,"published":"2026-07-30"},{"cvss_score":8.8,"headline":"Apache Kyuubi: Unauthorized directory access due to missing path normalization","id":"CVE-2025-66518","kev_date_added":null,"published":"2026-01-05"},{"cvss_score":8.1,"headline":"Apache Kyuubi: kyuubi.session.local.dir.allow.list bypass via unprefixed Spark file-conf aliases","id":"CVE-2026-62391","kev_date_added":null,"published":"2026-07-31"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-07-29","vendors":["Apache Software Foundation"]},"summary":"Remote attackers can exploit the Kyuubi Engine UI proxy to send HTTP requests to arbitrary hosts, enabling Server-Side Request Forgery attacks.","url":"https://insights.sbomify.com/CVE-2026-23904/"}
