Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-72642 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- elasticsearch (Bitnami): affected from 8.19.0; fixed in 8.19.20, 9.4.5, 9.5.1\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-2026-72642/ (Markdown: https://insights.sbomify.com/CVE-2026-72642/index.md)","id":"CVE-2026-72642","markdown":"https://insights.sbomify.com/CVE-2026-72642/index.md","name":"CVE-2026-72642","record":{"aliases":["BIT-elasticsearch-2026-72642","CLEANSTART-2026-AH85401","CLEANSTART-2026-XN90031","GHSA-2rm9-5cpg-f943","MINI-36j8-g4mf-67cq","MINI-4896-f5jv-r779","MINI-6j4x-7rrm-w42v","MINI-8944-ghj9-7fhq","MINI-gv9v-c5qm-rcj6","MINI-wrqh-42f7-x58h","MINI-x86g-xgrh-2m4w"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Elasticsearch ML inference","requires_auth":"low_privilege","summary":"A user with model upload privileges can trigger heap corruption in Elasticsearch's native inference process, potentially leading to arbitrary code execution or crashes.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"elastic","cpe":[{"product":"elasticsearch","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-823","name":"Use of Out-of-range Pointer Offset"}],"description":"The native inference process that Elasticsearch uses to evaluate uploaded machine learning models accepts a model operation that computes a memory address from an offset supplied inside the model, without validating that the offset stays within the bounds of the underlying storage. A user with the privileges required to upload and deploy a trained model can craft a model that reads and writes memory outside the intended allocation. The result is heap corruption that crashes the inference process, and, with sufficient control over the heap layout, could allow arbitrary code execution in the context of that process.","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":"Use of Out-of-range Pointer Offset in the Elasticsearch Machine Learning Native Inference Process","id":"CVE-2026-72642","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Bitnami","product":"elastic:elasticsearch","products":["elastic:elasticsearch"],"type":"memory_corruption","year":"2026"},"n_packages":1,"n_references":1,"next":{"headline":"Incorrect Authorization in Kibana Agent Builder Leading to Disclosure and Tampering of Private Agents","id":"CVE-2026-72643"},"packages":[{"ecosystem":"Bitnami","fixed":["8.19.20","9.4.5","9.5.1"],"introduced":["8.19.0","9.4.0","9.5.0"],"last_affected":[],"package":"elasticsearch","purl":"pkg:bitnami/elasticsearch","source":"BIT-elasticsearch-2026-72642"}],"prev":{"headline":"Incorrect Authorization in Kibana Leading to Unauthorized Modification of Data","id":"CVE-2026-72641"},"products":["Elasticsearch"],"published":"2026-08-13","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":"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":"total"},"state":"PUBLISHED","updated":"2026-08-14","vendors":["Elastic"]},"summary":"A user with model upload privileges can trigger heap corruption in Elasticsearch's native inference process, potentially leading to arbitrary code execution or crashes.","url":"https://insights.sbomify.com/CVE-2026-72642/"}
