Rest Nonce
The rest nonce can be apart of additional chained exploitation. This is, broadly speaking, a 1-time CSRF-token.
Exploitation
As an authenticated
user, the following GET request may be used to generate a new REST nonce token
to be chained in other exploits:
/wp-admin/admin-ajax.php?action=rest-nonce
This nonce value is sometimes reflected in the response header:
X-Wp-Nonce: 5bbcde1e4e
