Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-63259 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- kibana (Bitnami): affected from 9.4.0; fixed in 9.4.4\n- elk (Bitnami): affected from 9.4.0; fixed in 9.4.4\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-2026-63259/ (Markdown: https://insights.sbomify.com/CVE-2026-63259/index.md)","id":"CVE-2026-63259","markdown":"https://insights.sbomify.com/CVE-2026-63259/index.md","name":"CVE-2026-63259","record":{"aliases":["BIT-elk-2026-63259","BIT-kibana-2026-63259","GHSA-vv4j-vm47-33w3","MINI-3rcj-pw92-3vv8"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Kibana visualization tool","requires_auth":"low_privilege","summary":"Attackers can access unauthorized scheduled query results in Kibana Spaces by manipulating user-controlled keys, leading to information disclosure.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"elastic","cpe":[{"product":"kibana","vendor":"elastic"}],"cvss":{"score":4.3,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-639","name":"Authorization Bypass Through User-Controlled Key"}],"description":"Authorization Bypass Through User-Controlled Key (CWE-639) in Kibana can lead to information disclosure via user-supplied identifiers that reference scheduled query result data from Kibana Spaces the requester is not authorized to access.","ecosystems":["Bitnami"],"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":"Authorization Bypass Through User-Controlled Key in Kibana Leading to Information Disclosure","id":"CVE-2026-63259","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Bitnami","product":"elastic:kibana","products":["elastic:kibana"],"type":"missing_authorization","year":"2026"},"n_packages":2,"n_references":1,"next":{"headline":"Uncontrolled Resource Consumption in Kibana Leading to Denial of Service","id":"CVE-2026-63260"},"packages":[{"ecosystem":"Bitnami","fixed":["9.4.4"],"introduced":["9.4.0"],"last_affected":[],"package":"elk","purl":"pkg:bitnami/elk","source":"BIT-elk-2026-63259"},{"ecosystem":"Bitnami","fixed":["9.4.4"],"introduced":["9.4.0"],"last_affected":[],"package":"kibana","purl":"pkg:bitnami/kibana","source":"BIT-kibana-2026-63259"}],"prev":{"headline":"Denial of service in Eclipse Milo","id":"CVE-2026-63252"},"products":["Kibana"],"published":"2026-07-21","related":[{"cvss_score":9.8,"headline":"Kibana Arbitrary Code Execution","id":"CVE-2019-7609","kev_date_added":"2022-01-10","published":"2019-03-25"},{"cvss_score":9.9,"headline":"Kibana arbitrary code execution via prototype pollution","id":"CVE-2025-25015","kev_date_added":null,"published":"2025-03-05"},{"cvss_score":9.9,"headline":"Deserialization in Kibana","id":"CVE-2024-37288","kev_date_added":null,"published":"2024-09-09"},{"cvss_score":9.9,"headline":"Code injection in Kibana","id":"CVE-2023-31415","kev_date_added":null,"published":"2023-05-04"},{"cvss_score":9.8,"headline":"Information disclosure in Kibana","id":"CVE-2018-17245","kev_date_added":null,"published":"2018-12-20"},{"cvss_score":9.8,"headline":"Code injection in Kibana","id":"CVE-2018-17246","kev_date_added":null,"published":"2018-12-20"},{"cvss_score":9.1,"headline":"Kibana arbitrary code execution via prototype pollution","id":"CVE-2025-25014","kev_date_added":null,"published":"2025-05-06"}],"sources":[{"class":"attribution","licence":"Apache-2.0","name":"Bitnami","prefix":"BIT"},{"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":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-07-22","vendors":["Elastic"]},"summary":"Attackers can access unauthorized scheduled query results in Kibana Spaces by manipulating user-controlled keys, leading to information disclosure.","url":"https://insights.sbomify.com/CVE-2026-63259/"}
