## Why update_script_tag is rated Medium

This tool modifies existing data (script tags) reversibly without deleting it. However, the high severity reflects that script tags execute arbitrary code in the storefront environment, creating significant risk if an AI agent injects malicious JavaScript. While categorized as Write (data modification), the blast radius approaches Execute-level danger due to code injection potential.

From the tool's own definition: "Tool name 'update_script_tag' and description 'Update an existing script tag' indicate modification of stored configuration. Script tags in Shopify control JavaScript injected into storefronts, affecting customer-facing functionality."

## Use case

AI agents use update_script_tag to create or update resources in Shopify Graphql, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Shopify Graphql environment.
