🚨 Severity: HIGH
💡 Vulnerability: Third-party assets (KaTeX CSS and JS) were loaded from a public CDN (jsDelivr) without integrity attributes. This poses a supply chain risk (XSS/defacement) if the CDN is compromised and serves a malicious script, as the browser would execute it trustingly.
🎯 Impact: If exploited, attackers could inject malicious JavaScript to steal sessions, redirect users, or deface the application.
🔧 Fix: Added Subresource Integrity (SRI) integrity attributes with SHA-384 hashes for all external KaTeX resources in web/index.html. This ensures the browser only executes the scripts if their cryptographic hash matches the expected value. The required crossorigin="anonymous" attribute was properly maintained.
✅ Verification: Verify that the application continues to load correctly and that cargo check and cargo test pass successfully. In the browser network tab, you can inspect the resources to ensure they are fetched with the specified integrity constraint.
