A serious Safari bug disclosed in this blog post from FingerprintJS can disclose information about your recent browsing history and even some info of the logged-in Google account. From a report: A bug in Safari’s IndexedDB implementation on Mac and iOS means that a website can see the names of databases for any domain, not just its own. The database names can then be used to extract identifying information from a lookup table. For instance, Google services store an IndexedDB instance for each of your logged in accounts, with the name of the database corresponding to your Google User ID. Using the exploit described in the blog post, a nefarious site could scrape your Google User ID and then use that ID to find out other personal information about you, as the ID is used to make API requests to Google services. In the proof-of-concept demo, the user’s profile picture is revealed. FingerprintJS says they reported the bug to Apple on November 28, but it has not yet been resolved.
