原文摘录

摘自原文(1323 字符中的一小部分)
The `is_tree_granted` function in `fs_permission.cc` assumes that any path starting with two backslashes `\\` has a four-character prefix that can be ignored, which is not always true. This subtle bug leads to vulnerable edge cases.
原文中的代码
node --experimental-permission --allow-fs-read=C:\* -p "fs.readdirSync(Buffer.from('\\\\A\\C:\\Users'))"
