Earlier this month, a hacker who uses the online moniker msdian7 discovered that a new feature introduced by the HackerOne bug bounty platform had resulted in a vulnerability that could have been exploited to obtain any HackerOne user's email address.
The vulnerability could have been exploited for malicious purposes through HackerOne's demo programs.
"HackerOne provides demo programs for customers to experience the product as well as hackers to test against our production system. When you are a team member in a demo program, you can demo the report interface. In the report interface, you can invite an external participant to the report, which could be any user on the platform. By generating that invitation with a username and then viewing the invitation, the user's email could have been exposed," HackerOne explained.
Details of the vulnerability were disclosed by HackerOne last week.
This is not the first time HackerOne has awarded a significant bounty for a vulnerability found in its platform.
