Title
WWBN AVideo CSV Formula Injection via myComments.download.php
Summary
WWBN AVideo through commit c3edcc274c389816d434acadac07ee78eaf330c1 contains a CSV formula injection vulnerability in the myComments.download.php endpoint that fails to sanitize spreadsheet formula prefixes in comment text. Authenticated users can inject formulas starting with =, +, -, or @ characters that execute when administrators or video owners open the exported CSV file in spreadsheet applications.

Title
Snipe-IT before 8.7.0 CSV Formula Injection via Location-Scoping Export
Summary
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.

Title
Snipe-IT before 8.7.0 CSV Formula Injection via Asset Acceptance Report
Summary
Snipe-IT through 8.6.3 does not neutralize formula elements in the "unaccepted assets" acceptance report CSV export. ReportsController::postAssetAcceptanceReport builds the CSV by hand (stripping commas and joining rows manually) and, unlike the six sibling exports in the same controller, never applies League\Csv\EscapeFormula or honors the config('app.escape_formulas') setting. An authenticated low-privilege user with ordinary create/edit rights on any record whose free-text fields appear in the report (asset name/tag, company name, category, model, or assignee display name) can set such a field to a value beginning with =, +, -, @, tab, or CR. When a user with reports.view privileges requests the export (POST /reports/unaccepted_assets) for a pending checkout acceptance referencing the poisoned record and opens the resulting CSV in Excel, LibreOffice Calc, or Google Sheets, the injected content is evaluated as a formula in the downloader's spreadsheet context, enabling data exfiltration (e.g., HYPERLINK/WEBSERVICE) or, on legacy Windows Excel configurations, DDE command execution. Fixed in 8.7.0.

Title
exceljs through 4.4.0 CSV Formula Injection via Unescaped Cell Values
Summary
exceljs through 4.4.0 fails to neutralize leading equals, plus, minus, or at signs in cell values written to CSV output. Attackers who can influence exported cell values can inject formulas that execute when the CSV file is opened in a spreadsheet application, potentially exfiltrating data or performing other malicious actions.

Title
MongoSQL Transition Readiness Tool Improper Neutralization of Formula Elements in Generated Reports
Summary
The MongoSQL Transition Readiness Tool writes database and collection names into its generated CSV reports without neutralizing leading characters that spreadsheet applications treat as formulas. A user with write privileges on the cluster can choose a namespace name that is later evaluated as a formula when an operator opens the generated report in a spreadsheet application, which may result in unintended disclosure of report contents or execution of external content on the operator's workstation. Generating a report for the affected namespace and opening it in a spreadsheet application is required.

Title
Velociraptor CSV Formula Injection in Export Pipeline
Summary
When Microsoft Excel imports a CSV file, it executes cells beginning with certain characters as formulas, giving such CSV files arbitrary execution.
Velociraptor fails to sanitize such cells when exporting to CSV from various places such as the GUI, offline collector or data exports.
It is not clear if the vulnerability is actually in Microsoft Excel treating a CSV data file as executable content, or if Velociraptor should be sanitizing the data to prevent Excel from executing it. However, since this is such a common use case for Velociraptor we decided to highlight it in an advisory.

Title
Formula Injection in dool project
Summary
Dool in versions up to 1.3.8 is vulnerable to a CSV injection vulnerability when exporting data to a CSV file, as it fails to sanitize cell content beginning with special formula characters like =, +, -, or @. A local attacker can exploit this by running a process with a crafted name starting with =, which injects malicious formulas into the CSV output that execute when a victim opens the file in a spreadsheet application.

Mitigation
Implementation
When generating CSV output, ensure that formula-sensitive metacharacters are effectively escaped or removed from all data before storage in the resultant CSV. Risky characters include '=' (equal), '+' (plus), '-' (minus), and '@' (at).
Mitigation
Implementation
If a field starts with a formula character, prepend it with a ' (single apostrophe), which prevents Excel from executing the formula.
Mitigation
Architecture and Design
Certain implementations of spreadsheet software might disallow formulas from executing if the file is untrusted, or if the file is not authored by the current user.
No CAPEC attack patterns related to this CWE.
