An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2018-17247 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- org.elasticsearch:elasticsearch (Maven): affected from 6.5.0; fixed in 6.5.2\n- org.elasticsearch:elasticsearch (Maven): affected from 6.5.0; fixed in 6.5.2\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-2018-17247/ (Markdown: https://insights.sbomify.com/CVE-2018-17247/index.md)","id":"CVE-2018-17247","markdown":"https://insights.sbomify.com/CVE-2018-17247/index.md","name":"CVE-2018-17247","record":{"aliases":["GHSA-ccmr-qj26-845g"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":true,"product_category":"Elasticsearch","requires_auth":"none","summary":"An XXE vulnerability in Elasticsearch Machine Learning allows attackers to read local files if external network access is permitted in the security policy.","user_interaction":"not_required","vuln_class":"xxe"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"elastic","cpe":[{"product":"elasticsearch","vendor":"elastic"}],"cvss":{"score":5.9,"severity":"medium","source":"nvd","vector":"CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N","version":"3.0"},"cwes":[{"id":"CWE-611","name":"Improper Restriction of XML External Entity Reference"}],"description":"Elasticsearch Security versions 6.5.0 and 6.5.1 contain an XXE flaw in Machine Learning's find_file_structure API.
