# React 18 Security Modeling

## Summary
Model and mitigate security risks that arise from advanced rendering and hydration flows.

## Key Capabilities
- Identify XSS risks in streaming SSR and hydration.
- Validate safe handling of HTML and serialized data.
- Apply content security policies aligned with React 18 behavior.

## PhD-Level Challenges
- Formalize a threat model for concurrent rendering flows.
- Prove safety of serialization/deserialization pipelines.
- Evaluate CSP trade-offs for streaming responses.

## Acceptance Criteria
- Provide a React-specific threat model document.
- Demonstrate mitigation of a simulated injection attack.
- Document CSP configuration and impact analysis.
