services / Google Cloud / Google Cloud SQL

A Cloud SQL instance is a VM managed by Google that runs the SQL database instance (as well as any accompanying containers)

Cloud SQL is used to store and serve sensitive and application-critical data. Breach of a cloud SQL database can lead to exfiltration of highly sensitive data, or interruption of mission-critical applications.

cloudsql.​instances.​createTagBinding

A common use case of tag bindings is for use in IAM policy conditions. If the user has any policies that use tag bindings to enforce conditions, creating a tag on a resource allows them to escalate their access to that resource. Also requires getIamPolicy or knowledge of the IAM policy from some other means.

Risks

1. Privilege escalation (CRITICAL)
2. Denial-of-access (EVASION)

Scope: CRITICAL

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.
