CVE-2025-9571Network attack vector

Authenticated code execution via uploaded artifact deserialization

Published Dec 10, 2025 · Updated Dec 10, 2025

Deserialization of untrusted data in Google Cloud Data Fusion before 6.11.1 allows remote authenticated users to execute code in AppFabric. Google maps the flaw to CWE-502 but has not disclosed the AppFabric method or deserialization path that processes uploaded artifacts. Artifact-upload permission is required; successful exploitation grants control of the instance, including data access and pipeline modification.
