Title
Ninja Forms WordPress Plugin < 3.15.4 Server-Side Validation Bypass via List Fields
Summary
Ninja Forms plugin for WordPress before 3.15.4 contains an incomplete server-side validation vulnerability that allows unauthenticated attackers to submit arbitrary values to Checkbox List, Multi-Select List, Image List, Country, and State fields because NF_Abstracts_List falls through to a validate() method that only checks required-field presence. Attackers can submit crafted formula payloads through the unauthenticated nf_ajax_submit endpoint that bypass CSV escaping applied only to Textbox and Textarea fields, resulting in CSV injection when an administrator downloads and opens the exported submissions file.
