How to Fix CVE-2026-2473

To remediate this vulnerability, upgrade all affected Google cloud aiplatform dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

google-cloud-aiplatform fixed: 1.133.0 
pip install google-cloud-aiplatform>=1.133.0
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

pip show google-cloud-aiplatform

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2026-2473, inspect your installed packages using pip:

pip show google-cloud-aiplatform

Analyze the terminal output to locate any version of Google cloud aiplatform in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.133.0), your application is affected.

Note: The pip show google-cloud-aiplatform command checks currently installed packages in your active Python environment.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-340: Generation of Predictable Numbers or Identifiers, where the product uses a scheme that generates numbers or identifiers that are more predictable than required. In Google cloud aiplatform, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

Predictable bucket naming in Vertex AI Experiments in Google Cloud Vertex AI from version 1.21.0 up to (but not including) 1.133.0 on Google Cloud Platform allows an unauthenticated remote attacker to achieve cross-tenant remote code execution, model theft, and poisoning via pre-creating predictably named Cloud Storage buckets (Bucket Squatting). This vulnerability was patched and no customer action is needed.
