Never rely solely on front-end libraries for security. Secure your backend and frontend by encoding all user-supplied data before rendering it in the DOM. Ensure that characters like < , > , & , " , and ' are converted to their respective HTML entities. 4. Deploy a Content Security Policy (CSP)
After conducting a thorough analysis, we found that Bootstrap 5.1.3 is vulnerable to a CSS-based exploit. This vulnerability allows an attacker to inject malicious CSS code, potentially leading to unauthorized styling or layout modifications on a web page. bootstrap 5.1.3 exploit
