## Internal Security Audit Flags XSS Risk Across User-Generated Content
A critical internal security audit has been initiated to assess potential cross-site scripting (XSS) vulnerabilities across all user-generated content rendered by the application. The audit targets a wide attack surface, including practice item titles and notes, session notes, improvement notes, weak spots, assignment notes, focus areas, and user display names. While React's auto-escaping of JSX expressions provides a primary defense, the audit is a direct response to the risk that this protection could be bypassed in specific, high-risk scenarios.

The investigation is focused on identifying and eliminating any vectors that could circumvent React's built-in safeguards. The core verification points are the absence of the `dangerouslySetInnerHTML` property, ensuring no unsanitized user content is injected into `href`, `src`, or event handler attributes, and confirming user data is not used within `<script>` or `<style>` tags. A parallel check is mandated for server-side rendering processes to guarantee they do not inadvertently bypass the client-side escaping mechanisms.

Beyond the core XSS review, the audit scope extends to adjacent security concerns. This includes verifying that invite codes are sanitized before database lookups—though SQL injection via Prisma is considered safe—and ensuring email addresses are properly validated before being passed to the external Resend API. The formal acceptance criteria mandate a complete codebase audit for `dangerouslySetInnerHTML` usage and a verification that no user content is placed into URL attributes without prior sanitization, highlighting a systematic effort to lock down the application's security posture.
