How to report

All the bugs need to be reported at bugs@codechef.com

Here is what you need to take care of:

  • Please provide detailed reports with reproducible steps. If the report is not detailed enough to reproduce the issue, the issue will not be eligible for bounty.
  • In case of duplicacy, the report which is reproducible will be awarded a bounty.
  • Multiple bugs with one underlying issue will be awarded only to the earliest reporter.
  • NOTE: Bugs related to weak test case, ambiguity in statements, time limit of the problem statements won’t be considered as valid bugs and hence are not eligible for the program. Queries or feedbacks on the above mentioned topic should be commented on problem statement page itself.
  • A report regarding a missing security best practice are not eligible for bounty unless it can be exploited to impact the users directly. In that case, missing best practice report shall be eligible for bounty.
