🎯 What: The vulnerability fixed is Improper Output Neutralization in AppleScript strings within the show_dialog function.
⚠️ Risk: An attacker could provide a specially crafted message or title containing backslashes to escape the intended string context and execute arbitrary AppleScript commands.
πŸ›‘οΈ Solution: The fix adds .replace("\\", "\\\\") before .replace("\"", "\\\"") for both message and title, ensuring that backslashes themselves are properly escaped and cannot interfere with the string delimiters.


PR created automatically by Jules for task 11615348745991779792 started by @bearice

Properly escape backslashes in message and title before escaping quotes
to prevent breaking out of the string context in osascript commands.
In AppleScript, a trailing backslash can escape the closing quote,
allowing for arbitrary code execution.
