Title
Thelia before 3.1.2 and 3.2.x before 3.2.1 CSV Formula Injection via Exports
Summary
Thelia before 3.1.2 and 3.2.x before 3.2.1 contains a CSV formula injection vulnerability that allows unauthenticated visitors to inject spreadsheet formulas by supplying crafted registration, checkout or newsletter fields. Attackers can submit names, addresses or phone values starting with =, +, - or @ that CSVSerializer exports verbatim, executing formulas in the administrator's spreadsheet application.

Title
OpenPanel through 2.3.0 CSV Formula Injection via Cohort Member Export
Summary
OpenPanel through 2.3.0 contains a CSV formula injection vulnerability that allows unauthenticated attackers to embed spreadsheet formulas by supplying crafted profile IDs to the /track endpoint. Attackers can send tracking events with profile IDs like =HYPERLINK(...) matching a cohort, so exported cohort CSVs execute formulas that exfiltrate adjacent cell data.

Title
OpenClaw before 2026.8.1 CSV Formula Injection via Attendance Export
Summary
OpenClaw versions before 2026.8.1 fail to neutralize spreadsheet formula characters in participant display names within attendance CSV exports. Attackers can inject formula-like cells that execute with spreadsheet user permissions when the export is opened in formula-enabled applications.

CVE-2026-100563 (GCVE-0-2026-100563)

Title
OpenClaw before 2026.8.1 CSV Formula Injection via Session Labels
Summary
OpenClaw (npm package `openclaw`) before 2026.8.1 does not neutralize leading characters that spreadsheet applications interpret as formulas when the Control UI exports session data to CSV. Although session labels were quoted as CSV text, a lower-trust participant who can influence a session label or the first user message can place a formula-like cell in the Usage export; if an operator opens that export in a spreadsheet application with formula evaluation enabled, the cell may be evaluated with the permissions of the spreadsheet user. OpenClaw itself does not evaluate the formula, and practical impact depends on the spreadsheet application's security settings. The issue is fixed in 2026.8.1.

CVE-2026-93581 (GCVE-0-2026-93581)

Vulnerability from cvelistv5 – Published: 2026-10-12 06:49 – Updated: 2026-10-15 19:14
VLAI
Title
Insufficient Neutralization of Formula Elements in CSV Exports
Summary
User-controlled values are not sufficiently neutralized when included in CSV exports. Values originating from user input, including data submitted by authenticated users or received through external communication channels such as email, may be stored in fields that are later included in CSV exports. An attacker can therefore inject values beginning with spreadsheet formula characters such as =, +, -, or @. An attacker does not necessarily require an authenticated account if the affected field can be populated through an external input channel such as incoming email. When an affected CSV file is opened in spreadsheet software, the application may interpret these values as formulas instead of plain text. Depending on the spreadsheet application and its security configuration, a malicious formula may cause unintended actions, disclose information, or invoke external functionality. Exploitation may require the user opening the exported CSV file to confirm one or more security warning dialogs. The vulnerability does not execute code on the OTRS server; any additional impact occurs in the spreadsheet application used to process the exported file. This issue affects OTRS: * 7.0.X * 8.0.X * 2023.X * 2024.X * 2025.X * 2026.X before 2026.7.X Please note that ((OTRS)) Community Edition 6.x and before are vulnerable. Products based on the ((OTRS)) Community Edition also very likely to be affected

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.

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\u0027s spreadsheet context, enabling data exfiltration (e.g., HYPERLINK/WEBSERVICE) or, on legacy Windows Excel configurations, DDE command execution.

CVE-2026-86257 (GCVE-0-2026-86257)

Title
wger before 2.6 CSV Formula Injection via member export
Summary
wger before 2.6 fails to sanitize first_name and last_name fields in the gym member TSV export endpoint, allowing any gym member to inject spreadsheet formulas. Attackers can inject formulas like =HYPERLINK to exfiltrate admin data or execute code when admins open the exported file in Excel or LibreOffice Calc.

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.
