掲示板 Forums - A blank forum Topic (Resolved)

Apparently you can leave the title of a Topic blank and break a few things :D Not sure if there's a zero-width character, they deleted it afterwards, or the validation failed somehow?

(you can't expand it at all, because the link (title) is missing)

("Last Post:" is also blank, so you can't access the topic from there either. "View latest post" works.)

The topic in question: https://app.renshuu.org/forums...

It normally stops you from posting without a title though.

A bot would still need to run a client (not necessarily a full visible browser). I think you'd need to go out of your way to break validation, and I just don't see why anyone making bots would wanna do that. Anyway, this is almost certainly not a bot.

I did figure out how to replicated it. Apparently validation is extremely rudimentary so you can just enter a Space and it allows it... a little embarrassing honestly, no offence to Michael :)

It seems to strip it afterwards, but not when doing the validation. I'll test it a bit more.

Edit: Looks like you can also leave the body empty. Doesn't matter as much though.

You just need to strip whitespace when doing the validation. It's a super easy fix. Should take less than a minute. You just add a trim() and that's it.

Edit: There's also no link when you get a 好 point :D

The downstream effect is real with these "small" bugs. And yes, I would consider this a bug. At least as a programmer. Although I guess it doesn't really matter what you call it. I can live with "a design flaw that causes bugs".
