Detailed vulnerability description
The vulnerability allows a remote user to execute or persist actions beyond the caller's intended authorization.
The vulnerability exists due to improper privilege management in the MCP loopback feature when handling lower-trust caller input or configured input paths. A remote user can invoke the reachable feature path to execute or persist actions beyond the caller's intended authorization.
Only instances where the affected feature is enabled and reachable are vulnerable, and practical impact depends on whether lower-trust input can reach that path.
