## What is CVE-2025-9571?

CVE-2025-9571 is a high-severity unsafe deserialization vulnerability in Google Cloud Cloud Data Fusion, published on 10 Dec 2025. Any signed-in user can exploit it over the network, with no action from the victim.

### Official description

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 .

Weakness: CWE-502 (Deserialization of Untrusted Data)

Check this codebase for CVE-2025-9571 and fix it if it is affected.

What it is: CVE-2025-9571 is a high-severity unsafe deserialization vulnerability in Google Cloud Cloud Data Fusion, published on 10 Dec 2025. Any signed-in user can exploit it over the network, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2025-9571 in the wild and no public exploit code.

Affected product: Google Cloud Cloud Data Fusion. No package-level version data is available, so check the vendor advisory linked from the reference page.

Task:
1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.
2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.
3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.
4. Run the tests and summarise what changed and why.
5. If nothing in the project is affected, say so and change nothing.
