Summary

A user with query access to a Google Cloud Monitoring data source can use its resource proxy to send requests to other Cloud Monitoring API paths with the data source's credentials, and read data from any project those credentials can reach. When the data source forwards the user's OAuth identity or uses Workload Identity Federation, the impact depends on that credential's permissions. Fixed in Google Cloud Monitoring plugin 12.6.7.
