What an attacker can do

Attackers can send a crafted POST request to the admin-ajax.php endpoint with the nf_delete_all_data action and a per-site nonce to invoke migration routines that unconditionally iterate all blogs via switch_to_blog(), dropping all nf3_* tables and clearing options and transients across every subsite in the network without requiring super-admin or network-admin privileges. Vendor/CNA’s CVSS 4.0 assessment (base score 8.4/10) rates confidentiality impact as none; integrity and availability impact as high.
