Earlier quoted context omitted.

ideally, an auction and the vendor or a government can bid against malicious actors (which can also be a government). hard to set up though.

What kind of auction would you like to run? Remember that you can sell the same vulnerability to multiple people: it's software you can copy.

Maybe needs a Good-Guy-Buy-It-Now w/instant delivery at a fair price. (OK that’s kind of a threat—you’re running an auction and you have the price the corp has to pay to avoid the auction ending.)

$1k is so dumb and the fact we’re discussing auctions is proof (hello, Sundar, what you doing over there?).

Guess this will change after the next e.g. nationwide hospital ransomware by a hacker who publicly laments bounty rates, if the news cycle accommodates the story long enough.

Let'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…

Why is this 8.8?

It's because User Interaction is Required. CVSS 10 would be the case where everyone can be exploited without interaction.

Interestingly the 8.8 is more alert-worthy than the 9.8 and 10 cvss, because there is a need to be alerted of the current security risk, whereas with a cvss 2 vuln, there is nothing to be done by users, only admins.

> Ethical disclosure is a complicated topic, because researchers shouldn't hold bugs for ransom or demand high payment.

Why not? Capitalism requires they maximize their value. These profitable companies lay bare at the altar, so they should understand the requirements of their god.

There are plenty of people out there who find vulnerabilities and sell them to the highest bidder. Anyone is welcome to do it, including the researchers and hackers reporting them responsibly. There's no need to try and make a convoluted ethical justification. "I did this bad thing because you didn't pay me enough not to" doesn't work past the 6th grade.

Normalising 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.

I remember noticing this shift in nerd culture. In the early 2000s, it was common for people to say on places like Slashdot that they don't trust JavaScript and run their browser with it off. In the early 2010s, I noticed HN commenters thought this was insane, tinfoil hat type thinking.

It became insane because nothing bloody worked without Javascript some time in the early 2010s.

Like cellphones, javascript became necessary if you want to use webmail, access your bank's website, or whatever.

Only a score of 8.8?

RCE inside sandbox, so requires chaining with another 0day.

This doesn't affect the score though, the reason there's 1.2 points less than the max is because there is a Required User Interaction. The user needs to visit a specific html page.

Even with the sandbox protection layer, the rest of the parameters are maxed out.
