 Priority:  normal        |  Milestone:  Awaiting Review

--------------------------+-----------------------------
 When you log into the editor and manually remove the `wordpress_logged_in`
 cookie, any attempt to save or perform actions in the editor will trigger
 an infinite loop of API requests, resulting in a 403 Forbidden response
 with `rest_cookie_invalid_nonce`.

 Even after refreshing the page, these requests will persist, and the only
 way to stop them is to manually log out.

 This infinite loop of requests can spike your CPU to 100%, rendering your
 site unresponsive.

 Tested:
 * PHP - 8.3 and 7.4
 * Nginx
 * Laravel Herd 1.12.0 (locally) also on Ubuntu server 20.04.2 and 20.04.6
 * WP core - 6.1 - 6.7.1 (I didn't go further)
 * Plugin - none installed
 * Theme - twentytwentyfive, twentytwentyfour
