Before diving into specific fixes, it is crucial to understand how the Pro challenges differ from standard web wargames. The standard section often isolates a single vulnerability (like a basic SQL injection or a simple XSS). In contrast, the Pro section features:
Type the specific string required to trigger the "admin" condition, such as :admin . The resulting log entry will look like: [Your IP]:test :admin Use code with caution. Copied to clipboard
