⚡ A crafty loophole in Sketch before version 75 lets files slip through quarantine checks, meaning they’re downloaded and opened without a care in the world! Think of it like a hotel that lets in any package without checking the guest's ID—once the delivery is inside, it can do as it pleases. In this case, that means executing malicious commands as if they were invited guests. An attacker could craft a file that, once opened, executes arbitrary code on your machine. This could lead to a complete system compromise, where attackers have the same permissions as the user, wreaking havoc on your device!

In this case, that means executing malicious commands as if they were invited guests. This vulnerability allows files from library feeds to bypass the quarantine mechanism in Sketch, resulting in the potential for remote code execution through terminal commands.
