services / Google Cloud / IAM Roles

IAM custom roles created for use in IAM policies.

This is a sensitive service since it exposes information about organizational IAM policies and allows for potential manipulation of access.


Deleting a custom role is possible even when it's present in bindings. The bindings remain, but are ineffectual.



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.
