[Mission] Client Validation Bypass

🎯 Client Validation Bypass (Web · Level 1 · +75 XP)

A registration form uses an HTML5 "disabled" attribute and a client-side JavaScript regex to prevent submitting the privileged administrative access request. Intercept or modify the client state to submit the form.

Learning & Defense Goals:

• Inspect the disabled submit button in browser DevTools
• Remove the HTML restriction or invoke form submit
• Extract the server confirmation flag
