You're telling me that one of Bitcoin's biggest haters, who spent a decade crowing that we were all going to lose our money... is a failed banker who lost all of his clients' money?

🚨 CRITICAL - Unauthenticated RCE in React Server Components (GHSA-xqc2-xf4c-x3h3)

A critical vulnerability in React Server Components packages (react-server-dom-webpack, react-server-dom-turbopack, react-server-dom-parcel) allows unauthenticated remote attackers to execute arbitrary code via crafted RSC Flight payload responses transporting multiple typed arrays and attacker-controlled values.

👉 Affected: Versions 19.0.0–19.0.8, 19.1.0–19.1.9, 19.2.0–19.2.8, 19.3.0 | Upgrade immediately to 19.0.9, 19.1.10, 19.2.9, or 19.3.1 (or Next.js 16.4.1 / 15.5.28)

A cursory scan of my wrench attack repository shows that at least 4% of attacks are criminals attacking criminals, or victims of scams seeking retribution against the scammer.

The real number is likely higher. Don't do crime, it doesn't pay!

Please forward this announcement.
Following a wave of attacks, we have a number of security patches to push. Until then, it's better to err on the side of caution. 🙏
Updates to follow soon.
