back to article Bug in WebKit's IndexedDB implementation makes Safari 15 leak Google account info... and more

An improperly implemented API that stores data on browsers has caused a vulnerability in Safari 15 that leaks user internet activity and personal identifiers. The vulnerability was discovered by fraud detection service Fingerprint JS, which has contacted the WebKit maintainers and provided a public source code repository. As …

    Just puts the boots to Apple's claims about being concerned about "security" not their cash cow when they're talking the app store.

      Apple is only concerned about the perception of security, that's why their zero days stay open so much longer than anyone else's.

    Apple's decision to maintain its walled garden makes it vulnerable to problems when interacting with non-Apple software. Ideally they would collaborate more to anticipate, mitigate, and correct problems but this seems as likely as their starting to respond th ElReg's requests for comments.

      Apple's decision to maintain its walled garden makes it vulnerable to problems when interacting with non-Apple software.

      In other words, functioning as designed. The walled garden is there to prevent non-Apple software from interfering with Apple profits. Therefore, non-Apple software is strongly discouraged and deprecated. The ability to run non-Apple software will soon be removed.

      it would be a joke if this scenario was unthinkable

    Apple's lack of 3rd party browsers on iDevices should be criminal.

      (not available for iOS and iPadOS) ?? What? I have firefox on my iPhone running 15.1. Checks again, yup, there it is firefox next to the calculator and the decibel meter.

      And I'm pretty sure my iPad had both Chrome and Firefox before I turned it in to my employer last month.

        You do realize that all browsers on Ithings are mandated to use Safaris Webkit.

        You do right?

          Worryingly, the people commenting on The Register are better informed in these matters than the rest of the population, but still think don't understand the difference between the rendering engine and the browser UI.

            In chivo243's defence, OP (& he) mentioned only browsers. Not their underlying rendering engines.

            OP was wrong re browsers. As chivo243 pointed out. If you retcon OP's comment to be re rendering engines, then OP becomes right and chivo243 becomes wrong. But that requires retconning.

              From a developer's point of view, the rendering engine is the browser, and the UI is just a skin on top. It's like claiming two cars are different models because they're not painted the same color. Anyway, this article is about a security issue in the rendering engine, so it does not make sense to talk of the skin on top of the rendering engine.

                No. It isn't. That's like claiming two cars are the same because they share the same engine and chassis.

                The rendering engine is a massive amount of the browser, but the javascript runtime environment is equally important to a developer.

        Here’s a fact check for you, assuming you believe anything written at

        > Apple requires that all web browsers on iOS devices use Safari's WebKit rendering engine, which has made mobile browsers on iOS something of a monoculture: Though users may choose to run Chrome on iOS, it's essentially Safari under the hood.

        Firefox everywhere else uses the Gecko rendering engine. On iOS and iPadOS, it uses the WebKit engine.

    2. veti Silver badge

      It's more than that, it's wholly imaginary. There are several other browsers available on ios and iPad, including Firefox, Opera and more.

      1. Tessier-Ashpool

        All those other browsers rely on iOS webkit, which is the source of this particular vulnerability.

        Depending on your point of view, that’s a good or a bad thing. Personally, given that numerous other iOS apps and services depend on webkit, I’d say that centralising core code this way is for the best, even if the occasional howler surfaces.

      I do not understand the rationale of choosing to go with the more expensive and invasive of the evils. If you think Apple is really any better than Google, I direct you to a history of charges, claims, and lawsuits over the years, on a variety of issues.

      Apple just plays the public perception card of being "security conscious"; it doesn't mean they are any better than anyone else at actually implementing and enforcing security and quality software.

      Thank you for drinking Apple's kool-aid and paying your tithe for choosing an iThing instead of the cheaper and equally invasive eThing from an alternate vendor.

      They all reap you as their data feed. All of them. No exceptions. YOU are both market and product.

          Re: Whatever

          From a personal perspective I'd say they're as bad as each other. Yes, Google's business is the mining of personal information for advertising, but when it comes to security it has, at least among tech companies, an enviable track record of identifying and fixing bugs.

          As Apple moves more and more into the services business, it is going to be doing similar things with personal data for Apple Music and Apple TV. And, when it comes to patching software bugs, it has a dismal record, despite the solid underpinnings of MacOS. This is further not helped by the apparent need to fiddle with much of the open source software it makes use of: eg. when openssl bugs are discovered you normally need to wait for an OS update from Apple.

        They do *sort* of earn it in one area of the Mobile space, but only because the competition is so pathetic.

        If you get an iPhone, it'll be getting security updates for much, much longer than the majority of the Android alternatives (which might mean you can hate your dumbed down phone for longer).

      Way to misunderstand the issue

      This is not about a choice between web services controlled by Apple and web services controlled by Google. It's about a web browser controlled by Apple that will allow any web service to read data stored by any other web service.

          So, I suppose using the "clear history and website data" option in iOS settings for Safari between browsings (visit website, close tab, "clear all", open new tab, visit another site, close tab, "clear all", lather rinse repeat) will not help? (Because that'd be too easy, right?)

    "if one tab was used to access a user's bank and the other a malicious website"

    Question 1. Who would actually be dumb enough?

    Question 2. Should they rely on any software 'policy' to make it safe?

      Re: "if one tab was used to access a user's bank and the other a malicious website"

      can you clarify "who would be dumb enough" to what? open a bank site in a tab? the malicious site could be one that you normally trust, but has been tricked into doing something it shouldn't. sites that allow you to read your mail come to mind here.

      also, relying on policy to keep you safe. yes. it always comes down to that. there's a policy about which side of the road to drive on. this keeps you safe. there's a policy to not double-dip your chip. this keeps you safe.

    Private browsing mitigates this somewhat...

    Safari does private browsing a little differently than other browsers, in that each tab is its own session (FF/Chrome all seem to share the same 'private' session between tabs). The above demo would only work if you opened up gmail, signed in then went to that URL. But then again nobody except me seems to use private browsing day to day.
