Technical details

Ninja Forms version 3.14.8 and prior contains an incorrect authorization vulnerability (CWE-863) within its AJAX handling. The plugin uses a site-scoped capability check for the 'nf_delete_all_data' action instead of a network-wide check. An attacker with subsite administrator privileges can send a crafted POST request to 'admin-ajax.php' using a per-site nonce. This triggers migration routines that use 'switch_to_blog()' to iterate through all sites in the network, dropping 'nf3_*' database tables and clearing options/transients globally. The vulnerability is fixed in version 3.14.9.
