I’m slightly mad….

What stands in my way of having a nice vulnerability is the apparent inability of certain LLMs to emit \r (carriage return). For some reason they keep emitting \n (newline) instead.

I found myself posting this little comic at work A LOT currently.

It's really interesting, especially in the context of (agentic) AI, how features can be bugs or even vulnerabilities and vice versa, depending on whom you ask about it. It's always the context which matters and a lot is personal preference/risk appetite of whoever is using the 'feature'.

I tend to advocate for secure defaults with an option to let anyone choose if they want to take the risk of e.g. AI 'yolo' mode.

So I just met someone in person a few days ago. They said: "Oooh you're busy looking into AI stuff lately? That's good so you wont bother $THING with vuln reports! :P"

Guess where I just found a nice vuln :trollface:

Ich muss sagen ich bin schon ein bisschen beeindruckt wie smooth eine Onlinezulassung für ein Kfz läuft, ABER wenn ein einfaches & in den Eingabedaten so eine Fehlermeldung auslöst triggert mich das ein bisschen zu sehr ;). :cute_dumpster_fire:

Ich hab dann aber mal nicht an dem Ast gesägt auf dem ich saß.

Today I have a more serious topic than usual, please consider reposting for reach:

My wife and I are urgently looking for a specialist in neuropediatrics or a similar field for our autistic child with a diagnosed, but not further specified, movement disorder (myoclonus and/or spasms) to finally find a cause and, above all, an effective therapy. The symptoms are bothering our son ever since he’s born, now for more than nine years, seriously affecting his sleep. The usual processes and medical contact points have failed us unfortunately and he seems stuck in this condition.

We’re based in Berlin, Germany but really any contact with a specialist who would be willing to take on this case we’d be grateful for!

To reach use you can DM me or contact us via Email at unclear.condition@gmail.com

Soooo I built a little website based exploit for some CORS issue. Claude was really helpful to not only spit out a reasonably fast portscanner to use to find the target but also I used it to have a dark/light mode with a toggle and detection of the system default for the site.
