CVE-2018-8092
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedMautic before 2.13.0 allows CSV injection.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceMautic before version 2.13.0 is vulnerable to CSV injection, where specially crafted input containing spreadsheet formula characters (such as =, +, -, @) can be exported to CSV files. When users open these CSV files in spreadsheet applications, the injected formulas may execute arbitrary commands or exfiltrate data.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Check installed Mautic versionLocate the version file (app/config/version.yml or similar) or log into the Mautic admin dashboard and check the system information pageAffected if The installed version is below 2.13.0 (for example, 2.12.0, 2.11.0, 2.10.3, etc.)
-
Identify CSV export usageReview whether Mautic is used to export contact lists, segments, or campaign data to CSV format. Check export history or user activity for CSV generation.Affected if CSV export functionality is actively used and the Mautic version is below 2.13.0
-
Inspect custom fields for user-supplied dataIn the Mautic admin panel, navigate to Channels > Fields (or similar field management section) and identify custom fields that accept free-text input from users or contactsAffected if Custom fields accepting free-form text input exist and are exported via CSV, with Mautic version below 2.13.0
You are affected if your Mautic installation version is below 2.13.0 and you use CSV export with any custom fields that accept user-supplied text input.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped2.13.0
Upgrade Mautic to version 2.13.0 or later. Additionally, implement input validation to sanitize or escape special formula characters (=, +, -, @, tab, CR) in any user-supplied data before CSV export.
Mautic 2.13.0
- Backup your Mautic database and files before upgrading
- Ensure your PHP version meets Mautic 2.13.0 requirements (typically PHP 5.6.20+ or PHP 7.x)
- Download Mautic 2.13.0 from the official repository or composer
- Update your Mautic installation to version 2.13.0 using your preferred method (manual upload or composer update)
- Clear the Mautic cache after upgrade (delete contents of app/cache directory)
- Verify the upgrade was successful by logging into Mautic admin
- Test CSV import functionality to confirm the vulnerability is fixed
