• CVE-2026-2472: 0.61% estimated exploitation activity in the next 30 days; percentile 49.16 (FIRST EPSS, 2026-11-03). This is a model estimate, not proof of exploitation or customer exposure.

As published by the source; long descriptions are shortened.

Stored Cross-Site Scripting (XSS) in the genai/evalsvisualization 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.

# Patch Next advisory brief: CVE-2026-2472

Advisory: Google Cloud Vertex AI SDK affected by Stored Cross-Site Scripting (XSS)
IDs: CVE-2026-2472, GHSA-qv8j-hgpc-vrq8
Record: https://patchnext.com/advisories/cve-2026-2472 (revision 3, source checked 26 Oct 2026, 13:36 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: High (CVSS 8.6)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: google-cloud-aiplatform 1.131.0. A vendor fix does not mean a deployment is fixed.

## Affected components
- PyPI google-cloud-aiplatform: affected >= 1.98.0, < 1.131.0; fixed in 1.131.0

## Suggested inspection (read-only)
- `python -m pip show google-cloud-aiplatform`: prints the installed version. Run with the environment that serves production active.

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on google-cloud-aiplatform.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.
