WHAT IT DOES

What UpdateUserRoles does on Veeam VBR v13 MCP Server

AI agents use UpdateUserRoles to create or update resources in Veeam VBR v13 MCP Server, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Veeam VBR v13 MCP Server environment.

RISK

Why UpdateUserRoles is rated Medium

This tool modifies authentication and authorization metadata by editing role assignments. While reversible (making it Write rather than Destructive), it has high severity because role changes can grant or revoke access to critical backup/recovery functions across the Veeam infrastructure, affecting security posture and operational control.

From the tool's definition Tool name 'UpdateUserRoles' and description 'Edit roles assigned to a user or group' indicate modification of access control configuration. The verb 'Edit' explicitly signals a reversible write operation that changes user/group permissions.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs UpdateUserRoles safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Veeam VBR v13 MCP Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For UpdateUserRoles, this is the rule to start with:

UpdateUserRoles Rate-limited

UpdateUserRoles stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
