OpenSearch Data Prepper plugins trusts all SSL certificates by default

Published Oct 15, 2025

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.
