CVE-2023-25560Public exploitNetwork attack vector

System-account access via duplicate JSON key injection

Published Feb 10, 2023 · Updated Mar 10, 2025

JSON injection in DataHub before 0.8.45 allows remote authenticated users to obtain system-account access through crafted login data. The frontend AuthServiceClient interpolates user-controlled identifiers into JSON format strings, and Jackson resolves duplicate keys by accepting the last value. Valid user credentials or an invite token are required; injected identities can generate a system-user token or create a system account with full platform privileges.
