#curl 8.23.0 release candidate one is up: https://curl.se/rc/ Please take it for a spin and double-check that it works just as smooth as you would expect. Do not use release candidates in production. They are work in progress. Use them for testing and verification only. Use actual releases in production. Related
I had a look at the “project number of CVEs” that we estimated back at #curl up in late May. We then said it could end up at 55 by the end of the year. As we now already have published 45 and there are (at least) 20 coming, we have certainly exceeded those projections. The question is now rather if it will even be below 80 by the end of the year.

I've had to "unlock" my developer Apple ID once every 5 days on average for the past three months, and once per day for the past three days. Each time I do it, I have to perform a delicate dance to navigate what seems to be some kind of request throttling that gives me HTTP 503 responses during the unlock process, making it impossible to complete its several steps. Then my session times out and I have to start over. I've been trying to unlock my ID for about an hour so far this morning… Related

Now the thing is you can of course write examples in your documentation and Rust makes all examples into tests. This means that if you change the underlying code now your test fails. And so this means that you can't even you can't forget to update your examples in your documentation.

New supply chain attack this time for npm axios, the most popular HTTP client library with 300M weekly downloads. Scanning my system I found a use imported from googleworkspace/cli from a few days ago when I was experimenting with gmail/gcal cli. The installed version (luckily) resolved to an unaffected 1.13.5, but the project dependency is not pinned, meaning that if I did this earlier today the code would have resolved to latest and I'd be pwned. It's possible to personally defend against these to some extent with local settings e.g. release-age constraints, or containers or etc, but I thin… stepsecurity.io

The latest axios@1.14.1 now pulls in plain-crypto-js@4.2.1, a package that did not exist before today. This is a live compromise. This is textbook supply chain installer malware. axios has 100M+ weekly downl… Related

Something has changed recently in Safari (I have 18.6) where instead of asking you to confirm you want to connect insecurely to an HTTP server, it seems to try to automatically upgrade the connection to HTTPS and fail outright with an "unable to establish secure connection" without recourse if it can't.

korrents.com .
Under a name here, the quoted block is what they actually said.
The korrent beneath it is the claim those words support, in

About the English under a post
Some people here publish in a language other than English. Where they
do, this site shows a machine translation beneath the post, in
this typeface — the site's own, not theirs.
The post itself is never changed, moved or hidden: what is set in the
serif above is exactly what the person published, and it is what to
quote them on. A translation can be wrong in ways that matter,
especially about tone.
Only the post's own words are translated. A quoted post, a linked
article and a belief on korrents.com
are left in their original language.
