111-111: Consider improving boolean value displayThe current implementation displays the raw boolean value. For better user experience, consider converting to "Yes" or "No".
-validValue.textContent = prize_data.every_valid_submissions; +validValue.textContent = prize_data.every_valid_submissions ? "Yes" : "No";
85-85: Consider formatting the cash value for better displayFor improved readability, consider formatting the cash value with proper number formatting.
-cashValue.textContent = `$${prize_data.cash_value}`; +cashValue.textContent = `$${Number(prize_data.cash_value).toLocaleString()}`;
107-107: Fix minor typo in label textThere's a small typo in the label text - "Submission" should be plural.
-validLabel.textContent = "Reward All Valid Submission"; +validLabel.textContent = "Reward All Valid Submissions";

58-129: Excellent implementation for mitigating XSS vulnerability!The refactoring from using
innerHTMLto creating and appending DOM elements is a significant security improvement. This approach eliminates the risk of HTML injection attacks by:
- Using
document.createElement()to create DOM elements programmatically- Setting content with
textContentwhich treats input as literal text, not executable HTML- Using
addEventListenerfor event handling instead of inline handlers- Continuing to use
escapeHTML()for additional user input sanitizationThis implementation follows best practices for secure DOM manipulation.

@CodeRabbit Apart from best practices was the issue exploitable by any chance? |
