Recurring patterns

The bug types that recur here, drawn from past fixes, not open vulnerabilities.

Data Integrity: GraphQL response fields aliased to standard metadata keys like __typename and id can cause cache key confusion and incorrect object merging, potentially corrupting application state.

Reflected XSS: Serialized JSON state embedded directly into HTML scripts on the server side without escaping HTML-sensitive characters allows attackers to execute arbitrary scripts in the context of the user's browser.
