Given that the article says that prompts are modified like they are holy scripture, perhaps sell the prompt for $500k.

Zerodium used to offer up to 300k in 2021 https://www.securityweek.com/sites/default/files/images/Zero...
These brokers usually don't pay the bulk sum - they sell access to nation actors and you get payed out over time as long as the bug is not patched to discourage reselling and burning it. I doubt anyone would confirm if they got the full payment or not for something similar.

bink is correct. The people who buy exploits are governments. There is very little interest in Wordpress or indeed any target that isn't a browser or a mobile. Browsers and mobiles are the only things that are perennially useful to an intelligence agency. Those two are reliable access vectors for the vast majority of things that interest government organisations.
Comment by mschuster91 4 days ago
I'd disagree here. Still 41% of all sites use Wordpress [1]... and that means a lot of targets, and a lot of ways to target them. Your good ole' deface/ransomware extortion scheme, leaking data supposed to be confidential (such as account lists), trusted spreaders for exploits, or the latest hit, bets on "prediction markets" that have some Wordpress site set as oracle. People are willing to screw around with airport weather stations to manipulate bets [2], it's not that much of a stretch to assume such incentives would also apply for website hackers.

This is just 100% an incorrect assumption. Even just an e-commerce site running Woo has troves of potentially valuable customer data. Not to mention whatever else might be on the server, or what that server is connected to...

To show everyone the Gell-Mann amnesia effect in action.
When HN top karma poster and security professional posts something like this, doubles down, and can’t even be bothered to support it in any way (I’m open to learning and changing my opinion) it completely blurs the line going into social media influencer. Quantity over quality.

Just because they're exclusive about their clients doesn't mean they're not real. Their impact and effectiveness is a separate topic though. I don't think they're still actively operating or taking new clients, at least.
btw: "Oh, so you've done x?" What a snarky and confrontational way to ask someone something. Especially when it's asserting a well documented company and person is "not real".

But that’s besides the point. You straight up argued that one isn’t real in the most asinine way you could.
Even if you were right that would be ridiculous. The fact that you’re wrong and have multiple people telling you you are makes it even worse.
I’ve seen you replying in snide comments whenever someone disagrees with you before. Your status as…whatever you are doesn’t give you carte to treat randoms like they’re beneath you.

This is how all of these sites work. You would not get 500k for every exploit obviously. You would get that (or more) for great exploits.
I’m noticing you haven’t addressed anything I mentioned at all. Is that just acceptance that it’s the truth or are you just having a bad day?
Edit: Actually, let me add that for a 0click exploit on mobile devices that leads to root level permissions you’re very likely sitting on millions of dollars.

It sounds like you're telling me you believe you might get six figures for a "great" WordPress core RCE. I believe that's false, and I believe that for reasons that probably indicate our premises are much too far apart to hash this out here.
I have open contempt for online price list "brokers" like Zerodium. I do not have contempt for other commenters here. I think it's important that you understand the distinction before coming at me the way you've been in this thread. Disagreeing with me, rebutting or refuting me, sharply or ungenerously: totally fine. Your weird psychoanalysis of me: not fine.
Comment by ofjcihen 3 days ago
> Did you get mid-high 5 figures for a serverside vulnerability? I hear the Russians are paying $300k for Postfix! But the UAE might pay $400k through Crowdfense. These numbers are definitely real. How could they not be? They're right there on a web page.<
> Oh, you've done business with them then? Know someone who has?<
You’re replies have been snide and rude and you trying to pivot and say “you were merely talking about the brokers” is further showing you don’t care and feel entitled to continue.
Other users are calling you out on this behavior here and on other threads as well to the point that the comment you made starting this has stayed flagged.
Deflecting from someone calling out this consistent behavior is frankly ridiculous in the face of the receipts, especially trying to villainize the people calling you out for it.
Also, not even the main point anymore, but you’ve intentionally mischaracterized every argument others have put forwards including in your most recent response. I was extremely explicit about what kind of exploit commands a high price and you’ve chosen to again twist the argument to your desired conclusion:
> It sounds like you're telling me you believe you might get six figures for a "great" WordPress core RCE<
My “psychoanalysis” was an attempt at giving you grace but you seem intent on proving that talking down to others and then trying to sidestep justified criticism are default behaviors that you’re entitled to.

But what do you do in that situation? If they change the structure too much, then either they make it impossible to upgrade an existing site, or potentially break a whole bunch of things said sites depend on (mostly themes and plugins). And that ease of upgrading is likely what stops a lot of people just migrating away to other solutions.
Comment by 9dev 4 days ago
And since the WordPress foundation controls the extension marketplace, they can reliably determine which parts of the API surface are in use, or even invest a chunk of money every month to send AI-written patches to plugin maintainers to ease the transition.
There would be so many ways to improve the situation (to the benefit of WordPress maintainers, customers, and ecosystem vendors alike, mind you!), but alas, they are stuck to their ways and will not.

Alternatively, folks that aren't particularly technical hacking together a solution that works 'well enough' for what they need, and agencies that only have the interest/capacity to use one platform deciding that each and every customer needs to use that platform.
If you're a skilled programmer WordPress is probably not a good solution for your issues, but if you're more of a designer or hobbyist that wants a somewhat hacky extendable blog system it's pretty easy to use.

Please don't. There is absolutely no reason not to use the extremely simple and powerful combination of:
* a headless CMS / static website generated, of which there are a bunch so pick the one you like the most. My go-to is Hugo but it is somewhat complex
* a static hosting service with a generous free tier like CloudFlare Pages/Workers, Netlify, Firebase Hosting, etc.
Your blog costs nothing, has zero attack surface and zero maintenance.

Comment by 9dev 4 days ago
PHP can run the same code fully dynamically typed or with very strict type annotations, depending on your requirements. It has runtime reflection APIs that are so cheap that you don't really have to think about using them. You can do OOP or FP with PHP, or even procedural HTML-interleaved-with-PHP if that's your thing. It has late static binding, so you can defer to child classes from their parent class. There are generators and fibres as first-class language constructs now. Property hooks are an extremely clear pattern, way better than in many other languages.
Generally, there have been tons of new syntax extensions over the years, and they all slot in gracefully. With PHP 8.6, we're going to get partial application for functions, which will make PHP 8.5's match expressions one of the most ergonomic implementations I have seen yet!

You don't need many libraries in a typical project, because PHP is batteries-included and if you use a framework it does all the rest for you, that is true. But there are still hundreds of thousands of packages with billions of installs:

PHP might seem worse than other languages due to a combination of factors:
- It's the most used one by far, even though few of us like to admit it.
- Old tutorials still come up during web searches, so "SELECT * FROM `table` WHERE id = $id" will still be written today.

There are match expressions and arrow functions:
$slug = $title
|> trim(...)
|> (fn($str) => str_replace(' ', '-', $str))
|> (fn($str) => str_replace('.', '', $str))
|> strtolower(...);
There is meta-programming with annotations: final class PostsController
{
#[AccessControl(fn(Request $request, Post $post)
=> $request->user === $post->getAuthor()
)]
public function update(Request $request, Post $post): Response {
// ...
}
}
Native (and optionally value-backed) enums: enum Status
{
case Draft;
case Published;
case Archived;
}
Proper class property hooks, fully replacing getters and setters: class Data
{
public string $fullName {
get => "{$this->firstName} {$this->lastName}";
set(string $value) {
[$first, $last] = explode(' ', $value);
$this->firstName = $first;
$this->lastName = $last;
}
}
}
And tons of other features—among them asymmetric property visibility, fibres/green threads, DNF types, lazy object instantiation, an ever-improving yet fully opt-in static type system with runtime validation, a JIT compiler, an amazing package ecosystem and -manager, annotation-backed deprecation, and more.Comment by jorams 4 days ago
There is, but your example is not valid. You can't use short function syntax in constant expressions, it has to be an explicit `static function`.
The reason for this, IIRC (I can't find the GitHub issue or PR atm) is that these functions aren't allowed to close over any variables, and with fn syntax doing so is implicit. Rather than erroring they've disallowed the use of arrow functions entirely.

So this is some sort of ORM provided. $results = $wpdb->get_results( "SELECT * FROM {$wpdb->prefix}options WHERE option_id = 1", OBJECT );
> Some of the methods in this class take an SQL statement as input. All untrusted values in an SQL statement must be escaped to prevent SQL injection attacks. Some methods will escape SQL for you; others will not. Check the documentation to be sure before you use any method in this class. For more on SQL escaping in WordPress, see the section entitled Protect Queries Against SQL Injection Attacks below.It does not however prevent $wpdb users from NOT binding query parameters, which leads to this vulnerability.

I do understand it from an user perspective (it's easier to tell the average user to drag and drop rather than committing to a GitHub repo and letting hugo build the website), but from a security standpoint WordPress is really just waiting for a vulnerability (either in the core or on the thousands of plugins) in order to unlock its RCE-as-a-service functionality.

One thing I'm surprised about is that GPT-5.6 didn't block that prompt due to guardrails. My experience is that GPT-5.5 and up does not like offensive security work (similar to Opus 4.7+/Fable).

When Anthropic claimed Mythos chained 4 or 5 bugs to achieve sandbox escape and found bugs in core software, it sounded like bs. But here we are 2 months later seeing what they meant.
Cybersecurity was always a hard sell; security flaws were invisible - by contrast a fence with a hole is visible to everyone - anyone can ignore the locked gate and walk through the fence hole. With cybersecurity a hole in the fence may go unnoticed for years, maybe forever.
LLMs level the field. We will all benefit from more secure systems, a few people will get a lot of egg on their faces, and it will end the malpractice of underinvesting in software security to get a product out the door.
