CVE-2026-78837Public exploitNetwork attack vector

Database disclosure via injectable grid filter field

Published Sep 8, 2026 · Updated Sep 9, 2026

SQL injection in AppNitro MachForm 30 allows remote attackers to read sensitive database information through a crafted filter field. The grid_datasource.php endpoint uses filter[filters][0][field] in a query against an ap_form_{id} table, allowing valid column names to be enumerated. An unauthenticated network request reaches the flaw, and the demonstrated consequence is database-schema and sensitive-data disclosure.
