Caution
Description: A potential code injection vulnerability has been detected, where untrusted input is passed to a method that may execute arbitrary code. This issue allows attackers to inject and execute arbitrary code within the application, which could lead to unauthorized access to sensitive data or other malicious actions. To mitigate this, ensure that all user-supplied input is properly sanitized and validated before being processed. Avoid passing untrusted input to methods like eval, render etc, that can execute arbitrary code. Where possible, use safer alternatives such as parameterized queries or more controlled methods for handling user input. Learn more

The fix uses DOMPurify to sanitize the input before setting it as innerHTML, preventing potential XSS attacks by removing any malicious scripts from the input.

The fix replaces the direct assignment to innerHTML with a safer approach using textContent and DOM manipulation to prevent potential XSS attacks. It creates a temporary div element to parse the HTML string and then appends it to the courseList element.

Description: Log Injection occurs when untrusted user input is directly written to log files without proper sanitization. This can allow attackers to manipulate log entries, potentially leading to security issues like log forging or cross-site scripting. To prevent this, always sanitize user input using encodeURIComponent() or DOMPurify.sanitize() before logging. Learn more - https://cwe.mitre.org/data/definitions/117.html

Severity: High

The fix addresses the issue by implementing proper error handling when UIOptimizer fails to load. A new method handleUIOptimizerFailure() is added to gracefully degrade functionality by setting this.uiOptimizer to null and notifying the user about the limited optimization. This ensures that the application can continue to function with basic features even if the UIOptimizer fails to initialize.
