What exactly does "RCE inside sandbox" describe that goes beyond "the webpage can supply arbitrary JavaScript and the JavaScript engine executes it", but is still isolated from the system?
Memory isolation having one tab or account open on your bank and another on this page does not mean it could leak across the sandbox and steal bank account details but anything inside of your general page content can be lost

#92Let's take a moment to talk about the monetary value of this vulnerability. According to the Chrome release page ( https://chromereleases.googleblog.com/2026/09/stable-channel... ), Google paid a researcher $1000 for ethically reporting this. The CVE associated with it (CVE-2026-85046) is already being exploited in the wild. If we put our thinking caps on, how much do you think this vulnerability is actually worth? H…
Further: a vulnerability is probably not worth that much either, even if it's a hypercapable vulnerability, because the grey market buys full enablement kits, not vulnerability information. People making 6 figures on vulnerabilities are selling fully enabled full chain exploit systems, not just intelligence about a sandbox escape.

#94Normalising running arbitrary code delivered over the internet (in the form of JavaScript and WASM), as a necessary condition for accessing most web pages may not have been one of the best decisions we have made.
In the future we can ask that your JaveScript and Wasm comes with a proof of being benign.

While I agree 1000 is hilariously low for this, worth is hard to quantify. Do you pay what it could theoretically cost your company? the amount the top bidding bad actor would be willing to pay?
You let the market decide. Google could purchase the bugs on the same market blackhats do.
* They pay for vulnerabilities without reliable exploits (more for vulnerabilities that are demonstrably reliable).
* They don't require you to actually build a reliable exploit chain.
* They pay up front, not in tranches.
* They work with essentially all comers, unlike the grey market, where you're generally subcontracting to sell your first few.

I'd point out that part of the reason the grey and black market pays so well is because it is that type of market. You have to pay people extra to look past their morals and a risk premium against potential reputational and legal consequences.
That said, the gap is probably not just that.
