If you believe you have found a security vulnerability, please report it to us responsibly. Don't announce it in public places like GitHub issues or the forum. You can get in contact with us by:
- writing an email to bugs@e621.net (preferred)
- creating a vulnerability report on the e621ng repository (link)
Don't report through on-site DMails or Discord DMs, the two options above ensure that multiple people are notified. Include as much information as you can to help us understand the issue.
