Is setting CHMOD to 777 Dangerous?

chmod 777 777 means User, Group, and Others all have full read, write, and execute permissions. However, granting such permissions can pose a security risk.. You can type chmod 777, leave a space after it, and then drag the file or folder from Finder into Terminal. Terminal will fill in the correct path for you.

salju777, You almost never need 777 permissions on any type of file, and you absolutely never need 777 on a non-executable file. – skiphoppy Commented Apr 4, 2012 at 10:51.
