Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-102406 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- kibana (Bitnami): affected from 8.14.0; fixed in 8.19.22, 9.4.7, 9.5.4\n- elk (Bitnami): affected from 8.14.0; fixed in 8.19.22, 9.4.7, 9.5.4\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-2026-102406/ (Markdown: https://insights.sbomify.com/CVE-2026-102406/index.md)","id":"CVE-2026-102406","markdown":"https://insights.sbomify.com/CVE-2026-102406/index.md","name":"CVE-2026-102406","record":{"aliases":["BIT-elk-2026-102406","BIT-kibana-2026-102406","GHSA-gpr2-2mpc-hvf2","MINI-6cwj-pxx8-j4vw","MINI-7724-q964-7ff2","MINI-79g2-vf5w-j7g9","MINI-c2r3-rrqf-56v3","MINI-ffwj-j39j-3mf8","MINI-h836-8gwh-rhxv","MINI-p47j-j522-cpj2","MINI-wmwq-3g63-9w56"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["data_read","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"Kibana data visualization","requires_auth":"low_privilege","summary":"Attackers with Fleet privileges can hijack data streams to intercept and modify other tenants' data in Kibana deployments.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"elastic","cpe":[{"product":"kibana","vendor":"elastic"}],"cvss":{"score":8.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","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 could lead to cross-tenant data interception. In this context, \"tenant\" refers to a user or team sharing the same Kibana deployment, not a separate Elastic Cloud organization or customer. Kibana's Fleet package installation process allowed a user holding delegated Fleet package-management privileges, without direct Elasticsearch administrative privileges, to claim a data stream identifier already in use by another tenant. Because ownership of that identifier was not verified before Fleet applied the uploaded package's generated index and ingest-pipeline settings to already-existing infrastructure, an attacker could redirect an existing tenant's data stream through infrastructure under their control. This exposed the affected tenant's subsequently ingested data to unauthorized disclosure and modification, and prevented that data from reaching its intended destination. Interception could continue even after the malicious package was removed, requiring separate remediation of the affected infrastructure.","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 Cross-Tenant Data Interception","id":"CVE-2026-102406","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":"Incorrect Authorization in Elasticsearch Leading to Unauthorized Data Stream Modification","id":"CVE-2026-102407"},"packages":[{"ecosystem":"Bitnami","fixed":["8.19.22","9.4.7","9.5.4"],"introduced":["8.14.0","9.0.0","9.5.0"],"last_affected":[],"package":"elk","purl":"pkg:bitnami/elk","source":"BIT-elk-2026-102406"},{"ecosystem":"Bitnami","fixed":["8.19.22","9.4.7","9.5.4"],"introduced":["8.14.0","9.0.0","9.5.0"],"last_affected":[],"package":"kibana","purl":"pkg:bitnami/kibana","source":"BIT-kibana-2026-102406"}],"prev":{"headline":"Uncontrolled Resource Consumption in Elasticsearch Leading to Denial of Service","id":"CVE-2026-102404"},"products":["Kibana"],"published":"2026-10-06","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":"total"},"state":"PUBLISHED","updated":"2026-10-08","vendors":["Elastic"]},"summary":"Attackers with Fleet privileges can hijack data streams to intercept and modify other tenants' data in Kibana deployments.","url":"https://insights.sbomify.com/CVE-2026-102406/"}
