CVE-2025-9571 — A remote code execution (RCE) vulnerability exists in Google Cloud Data Fusion

High CVSS 8.7

A remote code execution (RCE) vulnerability exists in Google Cloud Data Fusion. A user with permissions to upload artifacts to a Data Fusion instance can execute arbitrary code within the core AppFabric component. This could allow the attacker to gain control over the Data Fusion instance, potentially leading to unauthorized access to sensitive data, modification of data pipelines, and exploration of the underlying infrastructure. The following CDAP versions include the necessary update to protect against this vulnerability: * 6.10.6+ * 6.11.1+ Users must immediately upgrade to them, or greater ones, available at: https://github.com/cdapio/cdap-build/releases .

Matched remediation archetype

Unsafe deserialization and object reconstruction

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Inventory serialization formats accepted from requests, queues, caches, files, cookies, and cross-service messages.
  • Trace whether untrusted input can select classes, types, callbacks, constructors, or object hooks during decoding.
  • Identify signing, schema validation, trust-boundary, and compatibility settings for each decoder.

Remediate safely

  • Replace native object deserialization with a data-only format and explicit schema validation.
  • If replacement is not immediate, use a safe decoder with a minimal type allowlist and disable polymorphic or executable hooks.
  • Update the affected library and add inert tests for unknown types, extra fields, malformed nesting, and unsigned data.
