Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2025-66518 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- org.apache.kyuubi:kyuubi-server_2.12 (Maven): affected from 1.6.0; fixed in 1.10.3\n- org.apache.kyuubi:kyuubi-server_2.12 (Maven): affected from 1.6.0; fixed in 1.10.3\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-2025-66518/ (Markdown: https://insights.sbomify.com/CVE-2025-66518/index.md)","id":"CVE-2025-66518","markdown":"https://insights.sbomify.com/CVE-2025-66518/index.md","name":"CVE-2025-66518","record":{"aliases":["GHSA-f8r6-6222-9pvc"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":true,"product_category":"Apache Kyuubi server","requires_auth":"low_privilege","summary":"Attackers can bypass directory restrictions to access unauthorized local files on Apache Kyuubi servers.","user_interaction":"required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"apache","cpe":[{"product":"kyuubi","vendor":"apache"}],"cvss":{"score":8.8,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:P/VC:H/VI:H/VA:L/SC:H/SI:H/SA:L","version":"4.0"},"cwes":[{"id":"CWE-22","name":"Improper Limitation of a Pathname to a Restricted Directory"},{"id":"CWE-27","name":"Path Traversal: 'dir/../../filename'"}],"description":"Any client who can access to Apache Kyuubi Server via Kyuubi frontend protocols can bypass server-side config kyuubi.session.local.dir.allow.list and use local files which are not listed in the config.\n\nThis issue affects Apache Kyuubi: from 1.6.0 through 1.10.2.\n\nUsers are recommended to upgrade to version 1.10.3 or upper, which fixes the issue.","ecosystems":["Maven"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Apache Kyuubi: Unauthorized directory access due to missing path normalization","id":"CVE-2025-66518","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Maven","product":null,"products":[],"type":"path_traversal","year":"2025"},"n_packages":2,"n_references":1,"next":{"headline":"Foxit pdfonline.foxit.com Stored Cross-Site Scripting in Layer Import Functionality","id":"CVE-2025-66519"},"packages":[{"ecosystem":"Maven","fixed":["1.10.3"],"introduced":["1.6.0"],"last_affected":[],"package":"org.apache.kyuubi:kyuubi-server_2.12","purl":null,"source":"GHSA-f8r6-6222-9pvc"},{"ecosystem":"Maven","fixed":["1.10.3"],"introduced":["1.6.0"],"last_affected":[],"package":"org.apache.kyuubi:kyuubi-server_2.12","purl":"pkg:maven/org.apache.kyuubi/kyuubi-server_2.12","source":"GHSA-f8r6-6222-9pvc"}],"prev":{"headline":"Apache Tika has XXE vulnerability","id":"CVE-2025-66516"},"products":["Apache Kyuubi"],"published":"2026-01-05","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":8.1,"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"},{"cvss_score":7.3,"headline":"Apache Kyuubi: Unrestricted access via Kyuubi engine-ui proxy","id":"CVE-2026-23904","kev_date_added":null,"published":"2026-07-29"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"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":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-01-05","vendors":["Apache Software Foundation"]},"summary":"Attackers can bypass directory restrictions to access unauthorized local files on Apache Kyuubi servers.","url":"https://insights.sbomify.com/CVE-2025-66518/"}
