THE RISK

Low Risk

Why liara_get_backup_download_url needs a policy

The tool performs a read operation by fetching a download URL for an existing backup. While the URL points to sensitive data (database backup), the tool itself does not execute backup operations, modify infrastructure, or perform destructive actions. The severity is low because retrieving a URL has no side effects on the system state, though access controls should protect the actual backup content.

From the tool's definition Tool name contains 'get' and description states 'Get download URL for a database backup'. This retrieves a URL resource without modifying, deleting, or executing operations.

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "liara_get_backup_download_url": {}
