Exploiting IndexedDB API information leaks in Safari 15
There’s a pretty nasty exploit in Safari 15, where sites/tabs that interact with an IndexedDB database leak that name to other tabs.

This is wild: while writing his own parallel-decodable PNG implementation, David Buchanan discovered he had a bug in his code.

Chrome vs. WordPress: All Text Showing as Glyphs / Symbols 🤯
Ever since mid december I’ve had a few reports from people that they were seeing my blog – the thing you’re reading now – rendered in unreadable text.
