CVE-2026-86745

Description
Snipe-IT is an IT asset management application. In Snipe-IT master-branch builds after 8.6.3 (the code was never included in a tagged release), SettingsController::downloadLocationScopingReport streams the FMCS location-scoping mismatch report (GET /admin/settings/location-scoping-report.csv) through a bare fputcsv() call without applying League\Csv\EscapeFormula, unlike the other CSV exports which honor config('app.escape_formulas'). An authenticated user with ordinary create/edit rights can place a spreadsheet formula in free-text fields that appear in the report (item name, asset tag, serial, item or location company name, location name) and arrange for the record to be FMCS-mismatched so it is included in the export. When a superuser downloads the report and opens it in Excel, LibreOffice Calc, or Google Sheets with formula evaluation enabled and external-content warnings dismissed or disabled, cells beginning with =, +, -, @, tab, or CR are executed in the victim's spreadsheet context, enabling data exfiltration (e.g., HYPERLINK/WEBSERVICE) or, on Windows Excel, legacy DDE command execution. This issue is fixed in version 8.7.0.
