CVE-2026-27442
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 · uneditedThe GINA web interface in SEPPmail Secure Email Gateway before version 15.0.1 does not properly check attachment filenames in GINA-encrypted emails, allowing an attacker to access files on the gateway.
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 confidenceThe GINA web interface in SEPPmail Secure Email Gateway versions before 15.0.1 fails to properly validate attachment filenames in GINA-encrypted emails, allowing path traversal or improper file access to the gateway's filesystem.

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.
-
Identify the installed SEPPmail Secure Email Gateway versionRun the command to display the product version, typically found in the system information page of the admin interface or via CLI: 'seppmail --version' or check the About section in the web management consoleAffected if The displayed version is below 15.0.1 (e.g., 14.x.x, 13.x.x, etc.)
-
Confirm the GINA web interface is accessible or enabledLog into the SEPPmail admin interface and navigate to the GINA configuration section, or check if the /gina endpoint is reachable on the gateway's web serverAffected if The GINA web interface is present and accessible on the system
-
Verify the system processes GINA-encrypted emails with attachmentsCheck the GINA configuration for active email processing rules, or review recent email logs for GINA-encrypted messages containing attachmentsAffected if The gateway is configured to receive and process GINA-encrypted emails with attachments
The environment is affected if the installed SEPPmail Secure Email Gateway version is below 15.0.1 AND the GINA web interface is enabled to process encrypted email attachments.
Generated from the published advisory. Verify against your own configuration.
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.
