CVE-2026-15159Network attack vector

Subscriber data disclosure via unchecked form identifier

Published Jul 17, 2026 · Updated Jul 17, 2026

IDOR in Saturday Drive Excel Export 3.3.6 and earlier allows remote authenticated users to download stored form submissions. The export handler accepts the user-controlled spreadsheet_export_form_id value as the form key without verifying that the requester is authorized to access the selected form. Subscriber-level access is sufficient to enumerate form identifiers and retrieve names, email addresses, phone numbers, physical addresses, and other stored form data in an XLSX file.
