Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-103009 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- elasticsearch (Bitnami): affected from 8.13.0; fixed in 8.19.23, 9.4.8, 9.5.5\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-2026-103009/ (Markdown: https://insights.sbomify.com/CVE-2026-103009/index.md)","id":"CVE-2026-103009","markdown":"https://insights.sbomify.com/CVE-2026-103009/index.md","name":"CVE-2026-103009","record":{"aliases":["BIT-elasticsearch-2026-103009","CLEANSTART-2026-QV23882","GHSA-jh46-59x3-g5qh","MINI-2v54-rgj4-wvj4","MINI-3645-2fq8-9f6r","MINI-38wp-6h32-xv2j","MINI-4xpp-xx8w-4vww","MINI-62qv-h2g5-c388","MINI-948w-6m96-hv76","MINI-9p6r-2q38-8g6v","MINI-cwgp-6p47-xx48","MINI-f996-hw3c-vvpx","MINI-g8wh-4392-ffc4","MINI-gw94-2hjx-3rqx","MINI-gx8q-mh3v-9w2p","MINI-mjm2-9mcf-rx55","MINI-q72v-fghj-7854","MINI-qpmq-jpcv-9vrj","MINI-v27p-89w9-8xrv","MINI-wpc9-448m-6fx5","MINI-wr8p-c58h-4wr9","MINI-wrmm-c25x-q6m2","MINI-x84h-24w8-wpjg","MINI-xfv2-whm5-rh2j"],"analysis":{"component_type":"database","fix_type":"patch","impacts":["data_read","data_modify"],"network_reachable":"yes","non_default_config":true,"product_category":"Elasticsearch search engine","requires_auth":"low_privilege","summary":"Attackers with cross-cluster API keys can bypass authorization to read or modify unauthorized indices via crafted search requests.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"elastic","cpe":[{"product":"elasticsearch","vendor":"elastic"}],"cvss":{"score":7.1,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:L/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 Elasticsearch can lead to Information Disclosure via a specially crafted cross-cluster search request that references an unauthorized shard identifier. Elasticsearch contains an authorization bypass weakness in its handling of cross-cluster search requests made through the Remote Cluster Security (RCS) 2.0 model. An authorization check validates a request against one identifying attribute of the target shard, while a separate, independently-supplied identifying attribute in the same request determines which shard is actually accessed. A holder of a cross-cluster API key authorized for one index can craft a request whose two identifying attributes refer to different indices, causing the request to be authorized against an index they can access while actually operating against a different, unauthorized index. This can expose that index's document contents, field mappings, and other metadata, and in limited cases allows modification of retention-lease state on the unauthorized index.","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 Elasticsearch Leading to Information Disclosure","id":"CVE-2026-103009","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Bitnami","product":"elastic:elasticsearch","products":["elastic:elasticsearch"],"type":"missing_authorization","year":"2026"},"n_packages":1,"n_references":1,"next":{"headline":"Heap-based Buffer Overflow in hMailServer","id":"CVE-2026-103010"},"packages":[{"ecosystem":"Bitnami","fixed":["8.19.23","9.4.8","9.5.5"],"introduced":["8.13.0","9.0.0","9.5.0"],"last_affected":[],"package":"elasticsearch","purl":"pkg:bitnami/elasticsearch","source":"BIT-elasticsearch-2026-103009"}],"prev":{"headline":"Uncontrolled Recursion in Elasticsearch Leading to Denial of Service","id":"CVE-2026-103008"},"products":["Elasticsearch"],"published":"2026-10-06","related":[{"cvss_score":9.8,"headline":"Elasticsearch Groovy Scripting Engine Remote Code Execution","id":"CVE-2015-1427","kev_date_added":"2022-03-25","published":"2015-02-17"},{"cvss_score":8.1,"headline":"Elasticsearch Remote Code Execution","id":"CVE-2014-3120","kev_date_added":"2022-03-25","published":"2014-07-28"},{"cvss_score":9.8,"headline":"Code injection in n/a","id":"CVE-2015-5377","kev_date_added":null,"published":"2018-03-06"},{"cvss_score":8.8,"headline":"Deserialization of Untrusted Data in Elasticsearch Leading to Remote Code Execution","id":"CVE-2026-72649","kev_date_added":null,"published":"2026-09-01"},{"cvss_score":8.8,"headline":"Use of Out-of-range Pointer Offset in the Elasticsearch Machine Learning Native Inference Process","id":"CVE-2026-72642","kev_date_added":null,"published":"2026-08-13"},{"cvss_score":8.8,"headline":"Privilege Escalation Flaw in Elasticsearch","id":"CVE-2020-7014","kev_date_added":null,"published":"2020-06-03"},{"cvss_score":8.8,"headline":"Improper Privilege Management in Elasticsearch","id":"CVE-2020-7009","kev_date_added":null,"published":"2020-03-31"}],"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":"2026-10-06","vendors":["Elastic"]},"summary":"Attackers with cross-cluster API keys can bypass authorization to read or modify unauthorized indices via crafted search requests.","url":"https://insights.sbomify.com/CVE-2026-103009/"}
