Rules

What the policy asks of you, and the bug types it won't reward, quoted from xpos's policy. "We" in these lines means the program, not this site.

While testing

  • For XSS, a simple alert(document.domain) should suffice.
  • Please only execute harmless code. Simply printing something or evaluating an expression should be enough to demonstrate the issue.
  • Report it as soon as you have a SQL error that indicates SQL injection.
  • Set the redirect endpoint to http://example.com .
  • Either attach a file to demonstrate the issue or paste the code in a code block in your report.
  • Please do not go against the guideline listed in the Disclosure policy section.
  • For issue types not mentioned try to adhere to the guide line and minimize the impact/disclosure.
