How it was found

Hi Team,

Summary:

First of all, i am not sure if a private program or any program have the capability to not show their response efficiency, but i assume they have because i saw some private programs that do not show response efficiency percentage on their public page.

Description:

Below list of private program was not showing their response efficiency percentage on their public profile, but using profile_metrics.json response, the percentage can be view resulting an information disclosure about the program.

█████████ = 100% ███████ = 100% ████ = 66% ████ = 68% ██████ = 52%

Steps To Reproduce

  1. Go to ██████████
  2. Observed that response efficiency was not visible
  3. Now go to █████████/profile_metrics.json
  4. I can confirm that 66% is the percentage of ██████████ because of this "response_efficiency_percentage":66

PoC screenshot below:

███████

Impact

Information disclosure despite the private program is not showing the response efficiency percentage.
