CSRF on https://apps.topcoder.com/wiki/users/editmyprofile.action

## Summary: Hi :) There is a CSRF on changing user details. ## Steps To Reproduce: There is no CSRF token or anything like that on https://apps.topcoder.com/wiki/users/editmyprofile.action . I added the poc html file below. When someone opens this html file, or we can add it into our website, victim's name and information will change. Note: This only works to signed-in users. Because unauthorized users cannot upload attachments. There is a mistake on https://apps.topcoder.com/wiki/login.action now. If you encounter an error, you can login on main site (https://accounts.topcoder.com/member) then try. ## Impact An attacker can force other users to change their name and informations without their knowledge.
