The NF_Abstracts_List class performs a validate() method that only checks for required-field presence. Unauthenticated attackers can submit crafted formula payloads to Checkbox List, Multi-Select List, Image List, Country, and State fields via the nf_ajax_submit endpoint. Because CSV escaping is only applied to Textbox and Textarea fields, these payloads result in CSV injection when an administrator downloads and opens the exported submissions file.</p> highadvisory
