services / Google Cloud / Google App Engine version

A version is a specific set of source code and configuration files that are deployed to a service.

Resources for a version, including source code, must first be uploaded to a Cloud Storage bucket.


Creating a version will deploy the provided source code to App Engine. This does not route any external traffic to the new version, but allows for resource hijacking.



This privilege may grant access to sensitive data from a significant fraction of organizational functions, allow interruption of critical organizational services, or its exploit could lead to significant privilege escalation.
