How it was found

Hello team, I noticed an issue in Directory where information of a soft-launched program getting disclosed!

I made this request as an unauthecated user,

GET /programs/search?query█████████&sort=published_at%3Adescending&page=1 HTTP/1.1
Host: hackerone.com
User-Agent: Mozilla/5.0 (Windows NT 10.0; WOW64; rv:47.0) Gecko/20100101 Firefox/47.0
Accept: application/json, text/javascript, */*; q=0.01
Accept-Language: en-GB,bn;q=0.5
Accept-Encoding: gzip, deflate, br
DNT: 1
X-CSRF-Token: <redacted>
X-Requested-With: XMLHttpRequest
Referer: https://hackerone.com/directory?query█████████
Cookie: <redacted>
Connection: close

and partial response was,

{"id":1913,"url":"/██████████","name":"████","meta":{"bug_count":5,"minimum_bounty":100,"soft_launched":true},"about":"","handle":"██████████","profile_picture":"https://profile-photos.hackerone-user-content.com/production/████████","internet_bug_bounty":false}

███████

This issue also disclose the Policy of that program! I've attached the policy as text.

Reproducible Steps:

  • Navigate to Directory
  • Search ████
  • Result will be, █████████

You won't see the bug count, policy and base bounty on result. but if you capture the request on BURP response, you'll be able to harvest these information from there!

Looking forward!
