Log out actions should be protected against CSRF

Description

Anyone can log you out of any WordPress install using CSRF (i.e. pointing you to the /wp-login.php?action=logout for that blog). This can aid in phishing attempts, and can have unforeseen security ramifications.

Log out actions should have their intention validated via nonce with fallback to AYS.

  • Owner changed from anonymous to markjaquith
  • Status changed from new to assigned

7790.002.diff introduces the wp_logout_url() and wp_login_url() functions to make themes simpler.

Adding a redirect parameter to those functions would be useful.
