- A podcast called Search Engine investigated a peculiar iOS bug where audio messages containing 'Dave and Buster’s' fail to send via the Messages app.
- The bug occurs because the audio transcription includes an unescaped ampersand ('&') in 'Dave & Buster’s', causing an XHTML parsing failure in MessagesBlastDoorService.
- The error is due to the ampersand not being properly escaped in the XHTML, which is required for special characters in HTML/XML.
- BlastDoor's strict parsing prevents potential security vulnerabilities by rejecting incorrectly formatted XHTML, demonstrating its effectiveness in thwarting exploits.
- The issue highlights the importance of proper data formatting in preventing parsing errors and potential security risks.
