There are a lot of major security vulnerabilities in the world that were made understandably, and can be forgiven if they're handled responsibly and fixed.

This is not one of them. In my opinion, this shows a kind of reputation-ruining incompetency that would convince me to never use Arc ever again.

On the other hand, this is pretty impressive:

    aug 25 5:48pm: got initial contact over signal (encrypted) with arc co-founder hursh
    aug 25 6:02pm: vulnerability poc executed on hursh's arc account
    aug 25 6:13pm: added to slack channel after details disclosed over encrypted format
    aug 26 9:41pm: vulnerability patched, bounty awarded
    sep 6 7:49pm: cve assigned (CVE-2024-45489)
Four hours from out-of-the-blue initial contact until a fix pushed is pretty good, even given how simple this fix probably was.

EDIT: Oh, the date changed; so it was 28 hours until fix. Still decent; and half an hour from initial contact to "Join our slack channel" is incredibly fast response time.

  • Rygian 10 months ago

    Reacting fast is the least the vendor could do. Bare minimum. This should not be applauded. It should be treated as "well, at least they reacted at a reasonable speed so the root cause was probably not malice".

    In other words, a quick turnaround with a fix does not lessen the impact of being negligent about security when designing the product.

    • gwd 10 months ago

      > Reacting fast is the least the vendor could do.

      It's certainly the least a vendor should do, but it's absolutely not the least a vendor could do, as we see the vast majority of vendors do far, far less. It's worth holding people up and saying, "This is how you should be doing it."

      • moosedev 10 months ago

        You’re technically correct, given a literal reading of the post you quoted, but the use of “could” there was idiomatic - let me explain:

        There’s a (fairly dated) idiom, “it’s the least I can do”, used when you are offering to do something to make up for a mistake or offense, but the person you hurt says your offer of compensation is unnecessary. For example:

        Situation: Person A bumps into Person B in the cafe, causing B to drop their coffee cup.

        A: I’m so sorry! Let me buy you another coffee.

        B: That’s not necessary - it was an accident, and I had almost finished my drink anyway.

        A: It’s the least I can do!

        B: Oh, thank you so much!

        Buying B a new coffee is not _literally_ the least A could have done - the least A could have done is nothing - but that’s the English idiom. “Can” is acting more like “should” here. You could read it as “It’s the least I can do (if I’m a good person, which I am)”.

The mandatory account just to try Arc was always a massive red flag to me - and led to me never trying it. Now I’m glad I didn’t!

      Ironically, that would help the privacy concerns since it would intermingle all traffic in their analytics system. Win-win!

  • bschmidt1 10 months ago

    No Linux version prevented me from trying it, didn't even get to the account wall, who knows if there's a pay wall. Perhaps the "moat" concept was misunderstood.

rpastuszak 10 months ago

Honestly I’ve always considered Arc to be a wolf in sheep’s clothing, especially when it comes to privacy.

50-60mm cash at 500mm (!) valuation and no business model is a big red flag when it comes to something as important, as personal as a browser. This is not a charity. Someone, somehow will have to pay for that.

  • danpalmer 10 months ago

    Yeah I’m so torn. It’s honestly the best browser UX I’ve seen, the right combination of vertical tabs, auto archiving, spaces/collections, sync, etc. I don’t care for Easels, but the core is good.

    Except… the growth hacks have started to creep in. They overlay an advert for their own AI services on top of regular Google search results pages in their mobile app. Not even a browser chrome UI element, it’s literally over the page content. That feels like a huge violation of what it means to be a browser.

    I don’t want their AI features. I don’t want growth hacks. I don’t want to sign in except for sync. I’d happily pay $40 a year for Arc as a product-focused-product, but as a VC-focused-product it’s heading downhill.

    • jwells89 10 months ago

      It does get a lot right and feels smooth in ways that Chrome, the various Chrome-clones, and Firefox just don't. It's also ironically the only browser even trying to feel native on Windows, using WinUI/WinAppSDK for its UI there, despite originally being Mac only.

      It's unfortunate that other cross platform browsers have such a strong tendency to phone in these little things, because they really do add up to make for a nicer experience.

    • mthoms 10 months ago

      I'm torn for the same reason: The UX hits all the right notes for me and I've tried every MacOS browser under the sun. I'm an ADHD sufferer and there's something about their combination of features and UI that just lets me get stuff done. And I don't even touch their AI features.

      This is all really sad news.

    • HungSu 10 months ago

      • danpalmer 10 months ago

        Thanks for the recommendation. I just had a quick try, it's nice, seems like a very polished Firefox. It seems to have a bunch of features I don't want in a browser so not sure if they'll get in the way.

    • rawsta 10 months ago

      Have you tried Vivaldi? It's really customizable and has a lot of features.

      • danpalmer 10 months ago

        Vivaldi feels like a cross platform port in all the ways I try to avoid. I understand the feature set is good, but it doesn't feel nice to use. Hard to state exactly why though.

aaomidi 10 months ago

You’d think that a company shipping a browser would pay a little more attention to security rules.

Also, shame on firebase for not making this a bit more idiot proof.

And really? $2500? That’s it? You could’ve owned literally every user of Arc… The NSA would’ve paid a couple more zeros on that.

  • prmoustache 10 months ago

    > You could’ve owned literally every user of Arc… The NSA would’ve paid a couple more zeros on that.

    only the 17 users they have.

    Shouldn't a government sue you if you try to sell him out vuln unless you personally know people in charge?

    • girvo 10 months ago

      Arc has a lot more than 17 users. It’s surprisingly popular.

    • netdevnet 10 months ago

  • nemomarx 10 months ago

    Are there a lot of Arc users? It seems like a pretty niche browser even compared to other niches.

    • viraptor 10 months ago

      Lots of developers and power users make a good chunk of Arc's use base. If you're after some interesting credentials then "every Arc user" is a perfect group with little noise.

      • nicce 10 months ago

        > power users

        Not that many. Most power users don't like to be forced for logging in, before they are able to use the browser.

    • shepherdjerred 10 months ago

      Having arbitrary browser access would be pretty valuable, even for just a small number of users.

    • Imustaskforhelp 10 months ago

      my brother uses arc browser , he is a developer . I think he saw it from somebody using it (maybe theo t3 or some other creator he watches) , and he found it cool (plus there were lot of videos flooded with saying arc is really great IDK)

      If someone finds something cool on the internet. They are going to try it , given that they are capable to do so.

      He had a mac so he was able to do so , Even I tried to run arc on windows once when it was really beta and only available to mac (I think now it supports windows not sure)

      I just kindly want to state that if the nsa could've bought this exploit , they could've simply waited and maybe even promote arc themselves (seems unlikely)

      Maybe they could've tried to promote the numbers of arc users by trying to force google and microsoft search engine through some secret shady company advertising / writing blog posts for arc / giving arch funding or like how we know that there are secret courts in america

      ( and since these search engines basically constitutes for a high percentage of discovery of stuff by search engine by users)

      People could've credited the success to arc in that case for getting more users but the real winner would've been NSA.

  • 255kb 10 months ago

    Firestore rules are in "lock mode" (no read or write allowed) by default since a long time. Then, everything is ultra well explained in the docs.

    I was already aware of it when being a noob dev 10 years ago, and could easily write a rule to enforce auth + ownership in the rules. No way, seasoned devs can miss that.

  • rmbyrro 10 months ago

    A couple? A vuln like this is worth >$1M very easily on the market.

  • Imustaskforhelp 10 months ago

    yes. I feel sad that now we have created an incentive where selling to the govt.'s is often much lucrative than telling to the vulnerable party (arc in this case)

    (just imagine , this author was great for telling the company , this is also a cross platform exploit with very serious issues (I think arc is available on ios as well))

    how many of such huge vulnerabilities exist but we just don't know about it , because the author hasn't disclosed it to the public or vulnerable party but rather nsa or some govt. agency

Also, firebase? seriously? this is a company with like, low level software engineers on payroll, and they are using a CRUD backend in a box. cost effective I guess? I wouldn't even have firebase on the long list for a backend if I were architecting something like this. Especially when feature-parity competitors like Supabase just wrap a normal DBMS and auth model.

  • JumpCrisscross 10 months ago

    > low level software engineers on payroll

    How does The Browser Company make money? They're giving their product away for free.

    Browsers are complicated. It doesn't inspire confidence that the folks in charge of that complexity can't get their heads around a business model.

    (Aside: none of their stated company values have anything to do with the product or engineering [1]. They're all about how people feel.)

      Unfortunately you are also describing Mozilla here.

    • bschmidt1 10 months ago

      Well, it's an app that users access all their online info through - bank, email, search, work, social - everything. Even an open-source, decentralized, blockchain, grass-fed, organic, extra virgin, written in nothing but HTML, released by W3C itself browser could monetize just ~5% of market share if users are downloading their build (or if its baked into the source), considering how much a browser reveals about its user and to the extent the user can be retargeted for: Ads, marketing, surveillance, analytics.

      The biggest opportunity has to be driving search traffic to the major search providers all these browsers partner with.

      Could also get acquired by a major browser vendor if you have a better product and people are downloading it more than the major ones, especially if both are based on the same underlying engine. Even Firefox still sucks to this day. I'm using it right now (Waterfox) the product still sucks! I know of some browser vendors acquiring others, especially as mobile took off and it was hard to get it right.

      Seems like the opportunity is similar to that of social media but slightly more modern because nobody uses new social media anymore but people are trying out new browsers (and you get richer user/usage data).

  • throwaway48540 10 months ago

    I don't see an issue, using something like Firebase is what a smart engineer would do. Just this one piece of logic is a problem.

    • notoverthere 10 months ago

      I tend to agree with this. Why re-invent the wheel by spending engineering effort building a CRUD backend?

      If you're trying to bring value to market, focus on your core differentiator and use existing tooling for your boilerplate stuff.

      • serial_dev 10 months ago

        It’s the “chrome replacement we have been waiting for”, but (if I read this right), my data is still sent to Firebase? Also it’s a browser, not a “tinder but for cats” startup idea I’m writing for my cousin for a beer.

        It’s not only not a smart engineering decision, it’s also a terrible product, reputation and marketing decision.

This convinced me to never use Arc again. I created a small guide to migrate from it to an open-source alternative: https://gist.github.com/clouedoc/4acc8355782f394152d8ce19cea...

TL;DR: it's not possible to export data from Arc, but it's possible to copy-paste the folder to a Chrome profile, and Firefox and other browsers will detect&import it.

  • Sakos 10 months ago

    Unfortunately, Zen Browser simply isn't an alternative. If you like Arc, then Zen's UI for tabs and splitting views isn't really anywhere close to satisfying the same needs.

    • EraYaN 10 months ago

      At least Firefox seems to be borrowing some of the UI features slowly. At least the Mozilla Foundation is very public with their wants and goals.

    • liamkearney 10 months ago

      I was literally using Arc because of the ability to hide most of the userchrome.

      Every time I open split views or tabs I curse. I've said this in the past but layering view multiplexors has to be the most stupid modern "super-user" trap. You have the ability to open multiple browser windows and composite them side by side, use it.

      Does anyone know of any other browsers that are chromium based and have very little features aside the ability to hide most of the UI?

I agree & disagree.

Browsers are very important part of our life. If someone compromises our browsers , they basically compromise every single aspect of privacy and can lead to insane scams.

And because arc browser is new , they wanted to build fast and so they used tools like firebase / firestore to be capable of moving faster (they are a startup)

Now I have read the article but I am still not sure how much of this can be contributed to firebase or arc

On the following page from same author (I think) https://env.fail/posts/firewreck-1 , tldr states

- Firebase allows for easy misconfiguration of security rules with zero warnings

- This has resulted in hundreds of sites exposing a total of ~125 Million user records, including plaintext passwords & sensitive billing information

So because firebase advocates itself to the developers as being safe yet not being safe , I think arc succumbed to it.

firestore has a tendency to not abide by the system proxy settings in the Swift SDK for firebase, so going off my hunch,

Also , you say that you have been convinced to never use arc again.

Did you know that chrome gives an unfair advantage to its user sites by giving system information (core usage etc.) and some other things which are not supposed to be seen by browsers only to the websites starting with *.google.com ?

this is just recently discovered , just imagine if something more serious is also just waiting in the shadows Couldn't this also be considered a major security vulnerability just waiting to be happen if some other exploit like this can be discovered / google.com is leaked and now your cpu information and way more other stuff which browsers shouldn't know is with a malicious threat actor ?

  • nine_k 10 months ago

    I very much agree with the idea that browsers are security-sensitive software, unlike, say, a picture editor, and more like an ssh server. It should be assumed to be constantly under attack.

    And browser development is exactly not the area where I would like to see the "move fast, break things" attitude. While firebase may be sloppy with security and thus unfit for certain purposes, I would expect competent developers of a browser to do due diligence before considering to use it, or whatever else, for anything even remotely related to security. Or, if they want to experiment, I'd rather that be opt-in, and come with a big banner: "This is experimental software. DO NOT attempt to access your bank account, or your real email account, or your social media accounts".

    With that, I don't see much exploit potential in learning stats like the number of cores on your machine. Maybe slightly more chances of fingerprinting, but nothing comparable to the leak through improper usage of firebase.

    • Imustaskforhelp 10 months ago

      hmm interesting. Other thing to add is if we treat it as a ssh server , we actually won't try to go out and break things.

      But I think that was the whole point of arc , to break the convention and be something completely new

      and I have a reason why

      They were competing with the giants called google , safari , firefox which have insanely large funding and their whole point was trying to sell something later built on this arc browser.

      and since chrome , firefox etc. don't try to come up with these ideas because well security reasons (which I agree to / as seen in the post)

      I think arc wanted to seperate itself from chrome / firefox and that's why they became a bit reckless you could say since this exploit was available.

      Also the other thing I want to convey , is that "With that, I don't see much exploit potential in learning stats like the number of cores on your machine"

      this was only recently discovered. Just imagine the true amount of exploits in these proprietory solutions which we don't know about.

      Yeh. Just like a ssh server , I would personally like the source code to be available but developing browsers is time consuming and money intensive for developers but ladybird exists , but its in beta.

      that being said , not open source is also that private , (xz) , but atleast it got discovered way quickly and was able to mitigate it quickly

  • prmoustache 10 months ago

    Yeah so using chrome based browsers like Arc is giving more power to Google to do shady stuff while also being a victim of the third party unsafe code.
