Agree. Chrome should just disable JIT by default and boom many website owner will start to optimize their website.

jira and confluence come to mind...

I suspect the people who agree to buy Jira & Confluence are not particularly heavy users of them. At least, that's the only explanation I can fathom for their continued sales.

In the past I would have thought this would incentivize finding bugs that might never be found. However it is now clear that all bugs that can be found will be found. So this makes a ton of sense.

So this makes a ton of sense. If Google can find all the bugs nowadays, presumably with AI, why still pay a bug bounty? At least by this logic, bug bounties make less sense now.

Because there’s still a sizable group of people who see $1,000 from Google as more than $1,000.

Even a resume item.

Which browser has a better security track record?

Despite what people are saying here, chrome has a really excellent track record. Nobody is perfect. Switching just because chrome got exploited one time will likely result in you switching to something worse. If you're paranoid, disable JIT.

Or disable JS altogether, and enjoy many sites working much quicker. Many others fail & need to be selectively allowed, but it's been worth it.

Well, someone did decide to tell google about this in exchange for a thousand dollars (albeit unclear how much the money was the motivator). Doesn't that mean the market did decide in google's favour?

Someone decided to tell Google about this in exchange for an unknown amount of money, chosen unilaterally by Google at a later date, at which point the market value of the vulnerability is $0. There's no way money is the motivator.

Money is not the only coin to pay someone in.

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…

this is why again, researchers should just honestly sell these to vuln brokers instead of donating them to trillion dollar companies for nothing. nothing will change until big tech can no longer rip off security researchers

But my “Google paid me” on my resume!

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.

Running code by itself isn't that bad, it's the fact that browser developers have decided for some reason that this code needs to be as performant as possible, so, JIT. I don't get it! The way JS is typically used, it doesn't even benefit from JIT all that much. Making ajax requests, doing stuff with strings, and moving DOM elements around doesn't need every CPU clock cycle to be used as optimally as possible. It's e…

I disagree about JIT performance not mattering. I enabled "Lockdown Mode" on iOS which disables the JIT for the mentioned security reasons, and it causes a very noticeable lagginess on many sites. Of course, the primary cause is the unnecessary JS monstrosities wasting CPU cycles. But practically speaking I can say that disabling the JIT results in a very subpar experience of many JS heavy pages.

Makes you wonder how many hacks wouldn't have occurred if security researchers (and vulnerability disclosure) was actually rewarded proportional to the possible/potential damage said vulnerability may have otherwise caused.

It's insulting how poorly incentivised white hats are, just look at how much North Korea is raking in with their cyber shenanigans - current estimates put it at around $6.75 billion to date (over the past 10 years or so).

For it to be memory safe, do you have to disable the JIT?

Yeah

It sounds technically possible to build a JIT where a verifier checks that the JIT-generated code is correctly pizlonated before allowing it to become executable. :)
