CVE-2023-27290Public exploitNetwork attack vector

Datastore read and write access via missing authentication

Published Mar 3, 2023 · Updated Mar 5, 2025

Missing authentication in affected IBM Instana Observability releases allows remote attackers with network access to read and write datastore data. The Docker-based deployment accepts unauthenticated native or HTTP queries on datastore service ports instead of enforcing configured credentials. Reachability requires network access to those backend services, exposing stored monitoring information to disclosure and modification without a reported availability impact.
