I found that these apps installed on my Mac are still vulnerable to the WebP exploit:

Arduino IDE, Keybase, Slack, and AdGuard for Safari.

The first 3 I haven't launched in months, but... it certainly was A Choice that "AdGuard *FOR SAFARI*" contains an entire copy of "Chrome/100.0.4896.160" inside it.

Roughly 2 weeks ago Google patched a critical vulnerability, CVE-2023-4863, that was being exploited in the wild. The broad impact of the root cause of the vuln and the fact that it will have a long tail of unpatched software has been poorly communicated. You can read more in @dangoodin 's [excellent article on Ars Technica](https://arstechnica.com/security/2023/09/incomplete-disclosures-by-apple-and-google-create-huge-blindspot-for-0-day-hunters/). As pointed out in the article above, Electron is based on Chromium and is impacted. Electron is bundled in a ton of apps that people might overlook. I threw together the following shell command to help macOS audit which versions of Electron apps are installed. ``` find /Applications -type f -name "*Electron Framework*" -exec \ sh -c "echo \"{}\" && strings \"{}\" | grep '^Chrome/[0-9.]* Electron/[0-9]' | head -n1 && echo " \; ``` When run, you should see something similar to the following: ``` /Applications/Visual Studio Code.app/Contents/Frameworks/Electron Framework.framework/Versions/A/Electron Framework Chrome/114.0.5735.289 Electron/25.8.1 /Applications/Slack.app/Contents/Frameworks/Electron Framework.framework/Versions/A/Electron Framework Chrome/116.0.5845.188 Electron/26.2.1 ``` #Security #Electron #CVE20234863 #CVE-2023-4863

@jwz last time I had a Mac from an employer I only used Safari once to download Firefox, I understand it's less plug-in friendly. The privacy badger from the EFF might have an early version in the works (my blocker of choice on Firefox)

I am almost afraid to ask... but who's blackmailing The Notorious JWZ to use Safari? Blink twice if you've been kidnapped.

@I my reasons have not changed since I last explained this 11 years ago https://www.jwz.org/blog/2012/04/why-i-use-safari-instead-of-firefox/
Why I use Safari instead of Firefox

Yesterday I posted a gripe about a particular bug in a particular piece of software I use, and the usual suspects wanted to turn that into a referendum on the healing, cleansing power of Open Source. So, since you obviously care, here's why I use Safari. There are both specific and general reasons, and I know ahead of time that all of this is going to be misinterpreted and taken out of ...

@jwz oh wow, sorry I totally missed that till now. Although I personally disagree with you on almost every opinion there, I admire the conviction. Hope you find the right blocker!
