Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2021-22145 exists.\n\nAffected packages and fixed versions:\n- org.elasticsearch.client:elasticsearch-rest-client (Maven): affected from 7.10.0; fixed in 7.13.4\n- org.elasticsearch.client:elasticsearch-rest-client (Maven): affected from 7.10.0; fixed in 7.13.4\n- elasticsearch (Bitnami): affected from 7.10.0; fixed in 7.13.4\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-2021-22145/ (Markdown: https://insights.sbomify.com/CVE-2021-22145/index.md)","id":"CVE-2021-22145","markdown":"https://insights.sbomify.com/CVE-2021-22145/index.md","name":"CVE-2021-22145","record":{"aliases":["BIT-elasticsearch-2021-22145","GHSA-q394-h7f5-7f44","UBUNTU-CVE-2021-22145"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Elasticsearch search engine","requires_auth":"low_privilege","summary":"Attackers can submit malformed queries to Elasticsearch to retrieve sensitive data from memory buffers, including documents and authentication details.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"elastic","cpe":[{"product":"elasticsearch","vendor":"elastic"},{"product":"communications_cloud_native_core_automated_test_suite","vendor":"oracle"}],"cvss":{"score":6.5,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-209","name":"Generation of Error Message Containing Sensitive Information"},{"id":"CWE-200","name":"Exposure of Sensitive Information to an Unauthorized Actor"}],"description":"A memory disclosure vulnerability was identified in Elasticsearch 7.10.0 to 7.13.3 error reporting.
