Spreadsheet data exfiltration via unsanitized export formulas
Published Aug 20, 2025 · Updated Aug 20, 2025
CSV injection in ELADMIN 2.0 through 2.7 allows remote authenticated users to plant formulas that exfiltrate data from exported spreadsheets. The exportUser path and 18 other export endpoints write fields beginning with =, @, +, or - into CSV/XLSX cells without neutralizing formula syntax. A user with permission to create exportable records must supply the formula, and a spreadsheet user must open and activate the malicious cell; the demonstrated payload discloses the system username through an external request.
