Nice SQLi vulnerability you got there ;-)

Well, yes, of course the whole app was written by an LLM. I’m not surprised at all.

There's no vulnerability here.

This is a client-side GitHub Pages app. GitHub Pages doesn't do server-side SQL execution.

As your POST request shows, it's querying the hackernews_history table on Clickhouse Playground which is a big read-only demo environment.

The information is public. "I can get the API wrapper to output more data" might be a quirk but it doesn't have security impact.

Kind of ironic that a vibe coded project is seemingly receiving vibe coded security reports already. Only a moment before all comments are vibed as well.

Well emsh, to be honest, I just coded it out of seeing if its possible or not and what the feedback was on it.

Now seeing the project having people be interested. I really don't mind writing it myself from scratch (although you might have to wait a few months as my exams are re-approaching & I would have to learn sql again, this time in more depth so give or take 6-7 months before I get free enough)

But honestly, I vibe coded it for myself to see how much words I wrote. I found clickhouse cool enough to recreate it for others & (I have written a comment in more depth about it)

It's really just a prototype. Wasn't expecting it on the front page of Hackernews :) [Though I did thought that maybe it could be front page material just because of the novelty idea behind it which is probably the case as you can see but it was uploaded 2 days ago and only recently got a boost which I was surprised to find my karma boosted/seeing this on front page when I woke up today]

> Only a moment before all comments are vibed as well.

regarding this. I see a lot of really great comments in here (written by human afterall) & this is honestly one of the best case scenarios for what I had in mind.

If vibe means relax comments, then I am all for it but if vibe means AI generated. Nah, I really hope so that Hackernews comments itself remains a place for humans.

(Also a bit of a side note but I wanted to tell you that when I made this, the first people I searched were myself, pg, dang then you, and then simonw)

(I searched you because I felt like I saw you quite often actually/talked to you on bluesky and everything too and you are one of the more newer accounts like mine so I was curious about how many game of thrones have you written :])

Have a nice day man!

I'm not though, been on HN on-off since 2010 or something :) Just a new account.

You have a nice day too!
