## What is CVE-2026-2472?

CVE-2026-2472 is a high-severity cross-site scripting vulnerability in Google Cloud Vertex AI SDK for Python, published on 20 Feb 2026. Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.

### Official description

Stored Cross-Site Scripting (XSS) in the _genai/_evals_visualization component of Google Cloud Vertex AI SDK (google-cloud-aiplatform) versions from 1.98.0 up to (but not including) 1.131.0 allows an unauthenticated remote attacker to execute arbitrary JavaScript in a victim's Jupyter or Colab environment via injecting script escape sequences into model evaluation results or dataset JSON data.

Weakness: CWE-79 (Improper Neutralization of Input During Web Page Generation)

Check this codebase for CVE-2026-2472 and fix it if it is affected.

What it is: CVE-2026-2472 is a high-severity cross-site scripting vulnerability in Google Cloud Vertex AI SDK for Python, published on 20 Feb 2026. Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.
Exploitation: There is no known exploitation of CVE-2026-2472 in the wild and no public exploit code.

Affected packages and fixed versions:
- google-cloud-aiplatform (PyPI): affected from 1.98.0; fixed in 1.131.0
- google-cloud-aiplatform (PyPI): affected from 1.98.0; fixed in 1.131.0
- google-cloud-aiplatform (PyPI): affected from 1.98.0; fixed in 1.131.0

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.
