Go 1.24's os.Root makes file security effortless:

root, _ := os.OpenRoot("/safe/path")
file, _ := root.Open("user/file.txt") // Automatically confined

No more:
• Manual path cleaning
• ../ vulnerability checks
• Security boilerplate

After:

go
os.OpenInRoot("/dir", userFile) // ✅ Done.
No CVEs. No fuss. Just secure by default.
