That means the attack is only relevant if a) you have a file with a secret, but no newlines&other characters breaking an URL, b) you know the path.
That seems rather unlikely in practice.

It may be that there are implementations that will ignore that and still open the URL. Or that will auto-encode newlines. Or that there's some trick I don't know. But that's all speculation. If you know of any *working* scenario where exfiltration with newlines works, I'd be interested to hear about it.

DOMPurify 3.3.0 will soon be released, with this likely being the most important change in a long time:

There's a way to invisibly compromise all software.

It's not just theoretical, and Ken Thompson showed us how.

My Dad's on the lookout for a reasonable e-book reader. No Android, no color, no LCD screen - eInk only.

It's been over a decade I last bought an ebook reader, and the Kindle Paperwhite we bought back then still functions great (it never connected to the internet), so I'm a bit out of my depth.

I was looking at a Kobo Clara BW, and I seem to recall reading favourable reviews of Kobo devices.

Is this a good one? Or is there any better one in a similar price range?

For various reasons, not interested in second hand devices, nor DIY or hacked customs. Dad needs something that can be bought off the shelf of a random local shop (or ordered online, shipping to Hungary without horrible tarrifs).

If you have a bash command line of "exec program ..." and you can control the "..." can you make it not run the exec and do something different? The answer is yes. Even if "..." is somewhat sanitised for shell metacharacters. If you can inject $[+] it will make bash error on that line and run the next. This is how https://dgl.cx/2025/10/bash-a-newline-ssh-proxycommand-cve-2025-61984 works.

This was driving me nuts: Even though I set #Firefox to always ask where it saves files, sometimes when I accessed PDF's it saved them in my Downloads directory without question.

It seems `browser.download.start_downloads_in_tmp_dir=true` solves this problem but I still can't wrap my head around why they implemented this exceptional behavior (and why there is no visible setting for it).

@badsamurai Great initiatives! Unfortunately they actively hinder C-levels blowing their remaining yearly budget in order to ask for more next year, so they won't happen.
