I'm willing to bet that this is linked to the magic __proto__ object namespace in JavaScript

The React Server Components wire format (Flight) is relatively novel and very new (it has existed in React stable for just a year). This is not a simple JSON parsing bug.

>AFAICT, they're AI generated.

What is the "tell"? I'm not saying they are or aren't, but... people say this about literally everything now and it's typically some flimsy reasoning like "they used a bullet point". I don't see anything in particular that makes me think ai over a standard template some junior fills out.

>the vulnerability was not found by a Wiz employee at all

I've re-read the Wiz article a few times. Maybe I'm just dumb, but where did Wiz claim to have found this vulnerability?

Hey mmsc, first of all - the blogs are not AI Generated!

Second of all, the blog did add more information

"In our experimentation, exploitation of this vulnerability had high fidelity, with a near 100% success rate and can be leveraged to a full remote code execution. The attack vector is unauthenticated and remote, requiring only a specially crafted HTTP request to the target server. It affects the default configuration of popular frameworks. "

In the end - if it helped spreading the news about this risk so teams can fix them faster, then this is our end-goal with these blog posts : )

There is some value:

> The vulnerability exists in the default configuration of affected applications

Can be inferred from the react blog but isn't really explicit

> According to Wiz data, 39% of cloud environments have instances vulnerable to CVE-2025-55182 and/or CVE-2025-66478.

Numbers!

Hey, researcher from Wiz here - we definitely didn't discover these vulns and all the credit goes to Lachlan Davidson. We have been investigating these vulns throughout the day and decided not to disclose the full extent of our conclusions or release a working exploit until more people get a chance to patch this (and as I mentioned in another comment, exploitation works out-of-the-box so you definitely should patch ASAP).
