Responsible disclosure

If you want to report a 'regular' bug, not related to security, please do so using our issue tracker.

We are committed to keeping the IT environment of S.A. Proto secure. This is why we ask you, if you find any bug and/or vulnerability related to the security of the IT environment of S.A. Proto, to:

  • disclose the bug to us, via, as soon as you confirm its existence;
  • not make any use of the bug and/or vulnerability beyond what is necessary to confirm it;
  • only access your own data to confirm the bug and/or vulnerability, where possible;
  • not publicly disclose the bug and/or vulnerability until we have had a chance to correct it.

If these conditions are adhered to, we promise in return:

  • to reply to your e-mail within 14 days;
  • to fix the vulnerability within 60 days after we acknowledge the vulnerability;
  • to give you credit for disclosing the bug and/or vulnerability;
  • to allow you to publicly disclose the bug and/or vulnerability after we have fixed it, if you so wish;
  • to not press any criminal charges.

Please keep in mind that this IT environment is run by volunteering students. While we take security incidents very serious, we don't have a dedicated, full-time team watching our security mailbox.

Known configuration issues

Due to the number of duplicate reports, please be sure to check the list below for known issues.

  • Our e-mail domains don't have any DKIM records present due to a technical incompatibility. We make do with SPF records.
  • There is no option to invalidate your own account sessions. We haven't found a way to make this work with our session driver and due to the low impact, we're leaving this as is.

PGP keys

Should you wish to encrypt your e-mail towards us you can use any of the PGP keys below:
