🚨 Severity: HIGH 💡 Vulnerability: The application was passing unvalidated HTML variables, specifically `generatedCitation.html`, to React's `dangerouslySetInnerHTML` prop in `src/components/wiki/citation-add-modal.tsx`. This could allow Cross-Site Scripting (XSS). 🎯 Impact: If a citation's contents originated from an untrusted source or were maliciously formatted, an attacker could execute arbitrary scripts in a user's session when the citation preview is rendered. 🔧 Fix: Imported `isomorphic-dompurify` and used `DOMPurify.sanitize()` to safely strip malicious scripts from the HTML payload before rendering it. ✅ Verification: Ran unit tests to verify no regressions were introduced. Evaluated that `isomorphic-dompurify` was already present in `package.json` as an existing dependency. Co-authored-by: aicoder2009 <[email protected]>
