{"cve":"CVE-2025-62371","nvd":{"published":"2025-10-15T18:15:39.897","modified":"2026-10-08T11:10:00.250","status":"Analyzed","description":"OpenSearch Data Prepper as an open source data collector for observability data. In versions prior to 2.12.2, the OpenSearch sink and source plugins in Data Prepper trust all SSL certificates by default when no certificate path is provided. Prior to this fix, the OpenSearch sink and source plugins would automatically use a trust all SSL strategy when connecting to OpenSearch clusters if no certificate path was explicitly configured. This behavior bypasses SSL certificate validation, potentially allowing attackers to intercept and modify data in transit through man-in-the-middle attacks. The vulnerability affects connections to OpenSearch when the cert parameter is not explicitly provided. This issue has been patched in version 2.12.2. As a workaround, users can add the cert parameter to their OpenSearch sink or source configuration with the path to the cluster's CA certificate.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N","score":7.4},"cwes":["CWE-295"],"references":["https://github.com/opensearch-project/data-prepper/commit/98fcf0d0ff9c18f1f7501e11dbed918814724b99","https://github.com/opensearch-project/data-prepper/commit/b0386a5af3fb71094ba6c86cd8b2afc783246599","https://github.com/opensearch-project/data-prepper/commit/db11ce8f27ebca018980b2bca863f7173de9ce56","https://github.com/opensearch-project/data-prepper/security/advisories/GHSA-43ff-rr26-8hx4"],"products":["amazon:opensearch_data_prepper"],"source":"nvd","synced_at":"2026-10-19T22:12:35.277909958+00:00"},"epss":{"cve":"CVE-2025-62371","score":0.00195,"percentile":0.09137,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-43ff-rr26-8hx4","url":"https://osv.dev/vulnerability/GHSA-43ff-rr26-8hx4","summary":"OpenSearch Data Prepper plugins trust all SSL certificates by default","modified":"2025-10-16T08:12:47.192382Z","packages":[{"ecosystem":"Maven","name":"org.opensearch.dataprepper.plugins:opensearch","purl":"pkg:maven/org.opensearch.dataprepper.plugins/opensearch","ranges":["<2.12.2"],"fixed":["2.12.2"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
