Recurring patterns

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

Cross-Site Scripting (XSS): The JSON formatting filter failed to escape HTML-sensitive characters like '<' and '>', allowing raw JSON strings embedded in `<script>` tags to break out of context and execute arbitrary JavaScript. Developers must ensure that all structured data serialization filters output safely escaped unicode sequences rather than raw characters.
