A few months ago I mentioned in a thread about Piefed there were questionable system design choices that indicated that other parts of the system should be carefully examined for how they’re handling and sanitizing input. I'm assuming someone discovered one of the places that this was actively exploitable.
From what I've seen of the code, although Python is not my specialty, it might be worth delaying reactivation until it can demonstrate that it is at least somewhat resistant to the OWASP Top 10, especially Injection.
Irresponsible disclosure is annoying, but vastly better than discovery and exploitation by those who aren't going to disclose at all.
