Impossible to login with passwords that contain trailing or leading spaces
|Reported by:||rpattillo||Owned by:||nacin|
It is possible to set a user's password to a string that includes leading or trailing spaces. The spaces will be hashed with the password as it is saved. During login attempts, the spaces will be trimmed before hashing, making it impossible to log in again.
1] Log in.
2] Navigate to /wp-admin/profile.php to edit your profile.
3] In the new password and confirmation fields, enter any password followed by trailing spaces.
5] Try to log in using the new password with trailing spaces and without.
What is expected:
The password without trailing spaces should work. This would be in line with what happens if the password is changed via the lost password system, and the new password has trailing or leading spaces.
What actually happens:
Neither the password without trailing spaces nor the password with the same trailing spaces will work. It will be impossible for the user to login until the password is reset again.
This is similar to ticket #23494. The resolution there was to trim the password in wp_set_password() before passing it to wp_hash_password(). However not all methods of changing the password go through wp_set_password().
