Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-102411 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- elasticsearch (Bitnami): affected from 8.0.0; fixed in 8.19.23, 9.4.7, 9.5.3\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-2026-102411/ (Markdown: https://insights.sbomify.com/CVE-2026-102411/index.md)","id":"CVE-2026-102411","markdown":"https://insights.sbomify.com/CVE-2026-102411/index.md","name":"CVE-2026-102411","record":{"aliases":["AZL-106721","BIT-elasticsearch-2026-102411","CLEANSTART-2026-JZ62196","GHSA-qvfh-5p79-6753","MINI-2rcr-5vxv-8f26","MINI-32mc-hh7m-jgr3","MINI-58gq-hcv8-65h7","MINI-64m2-r7gg-366x","MINI-6p27-252w-vxvx","MINI-7h59-6gm6-fm58","MINI-7r2v-hjrr-6967","MINI-83v6-wc6r-x5h6","MINI-9p66-8mg8-55r2","MINI-cj52-gw76-8rh6","MINI-fhvh-qvw5-r3vx","MINI-g2gj-84vg-63vh","MINI-hr5h-57xc-c8fw","MINI-jfwv-c852-wgf6","MINI-pv54-qpxr-qv8w","MINI-q93g-cp8m-5234","MINI-r655-m5g7-gjmc","MINI-rfq7-pr8f-vgj9","MINI-rmrx-7qrm-gfcm","MINI-rwqc-9588-2pr6","MINI-v837-2qvf-wrmm"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Elasticsearch search engine","requires_auth":"low_privilege","summary":"A user with manage_index_templates privilege can cause denial of service by registering multiple templates that exhaust heap memory when retrieved together.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"elastic","cpe":[{"product":"elasticsearch","vendor":"elastic"}],"cvss":{"score":6.5,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-770","name":"Allocation of Resources Without Limits or Throttling"}],"description":"Allocation of Resources Without Limits or Throttling (CWE-770) in Elasticsearch can lead to Denial of Service via Excessive Allocation (CAPEC-130). Elasticsearch enforces a size limit on the user-supplied metadata field for each individual template resource, but does not limit the total memory used when multiple such resources are retrieved together. A user holding the *manage_index_templates* cluster privilege can register multiple resources each within the individual limit. Retrieving them together materializes all of their metadata values in memory at once, exhausting available heap and causing the affected node to fail with an out-of-memory error, resulting in a denial of service.","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":"Allocation of Resources Without Limits or Throttling in Elasticsearch Leading to Denial of Service","id":"CVE-2026-102411","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Bitnami","product":"elastic:elasticsearch","products":["elastic:elasticsearch"],"type":"denial_of_service","year":"2026"},"n_packages":1,"n_references":1,"next":{"headline":"Incorrect Authorization in Kibana Leading to Sensitive Information Disclosure","id":"CVE-2026-102412"},"packages":[{"ecosystem":"Bitnami","fixed":["8.19.23","9.4.7","9.5.3"],"introduced":["8.0.0","9.0.0","9.5.0"],"last_affected":[],"package":"elasticsearch","purl":"pkg:bitnami/elasticsearch","source":"BIT-elasticsearch-2026-102411"}],"prev":{"headline":"Missing Authorization in Kibana Leading to Information Disclosure","id":"CVE-2026-102410"},"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":"A user with manage_index_templates privilege can cause denial of service by registering multiple templates that exhaust heap memory when retrieved together.","url":"https://insights.sbomify.com/CVE-2026-102411/"}
