CVE-2026-39537
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 · uneditedUnauthenticated Local File Inclusion in Mikado Core <= 1.6 versions.
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 confidenceUnauthenticated Local File Inclusion vulnerability in Mikado Core versions 1.6 and below allows remote attackers to read arbitrary files on the server by manipulating file path parameters without requiring authentication.

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 Mikado Core installationCheck for Mikado Core by examining web application banners, source code comments, or installation directories. Look for 'mikado', 'mikado-core', or related naming in the web root. Query the application for version information via admin panels, API endpoints, or version files if accessible.Affected if Mikado Core is installed and version is 1.6 or lower (1.6, 1.5.x, 1.4.x, etc.)
-
Locate file path parameter handlersSearch web application source code for functions that accept file path inputs, such as include(), require(), file_get_contents(), or similar file operations. Look for parameters that might accept 'file', 'path', 'page', 'template', 'load', or similar names in HTTP requests.Affected if File path parameters exist that accept user-controlled input without sanitization
-
Verify unauthenticated access is possibleTest if file path manipulation endpoints are accessible without authentication. Attempt to access known file inclusion endpoints without providing credentials or session tokens.Affected if File path parameters are accessible without authentication (no login required)
-
Check for file inclusion vulnerabilityAttempt safe, read-only tests using known file paths (e.g., /etc/passwd on Linux, boot.ini on Windows) via suspected file path parameters. Use relative paths and null byte injection if applicable. Observe if file contents are returned in the response.Affected if Arbitrary file contents are returned when manipulated paths are submitted, confirming LFI is present
You are affected if Mikado Core version 1.6 or below is running and file path parameters are accessible without authentication, allowing unauthorized file reads.

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.
From vendor dataUpdate Mikado Core to a patched version. If immediate update is not possible, implement strict input validation on file path parameters and restrict filesystem permissions to prevent unauthorized file access.
