Official description
OpenMetadata is a unified metadata platform. Prior to version 1.12.4, a non-admin SSO user can trigger a TEST_CONNECTION workflow for a Database Service and receive, in the HTTP 201 response of POST /api/v1/automations/workflows, both the cleartext database password in request.connection.config.password and the ingestion bot JWT in openMetadataServerConnection.securityConfig.jwtToken. The leaked ingestion-bot token can then be reused as Authorization: Bearer <jwt> to access sensitive service APIs with bot-level privileges. This issue has been patched in version 1.12.4.
