CVE-2026-6569
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 · uneditedA vulnerability was identified in kodcloud KodExplorer up to 4.52. This impacts the function fileGet of the file /app/controller/share.class.php of the component fileGet Endpoint. Such manipulation of the argument fileUrl leads to improper authentication. The attack can be launched remotely. The vendor was contacted early about this disclosure but did not respond in any way.
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 confidenceA path traversal and authentication bypass vulnerability exists in KodExplorer up to 4.52 in the fileGet function within /app/controller/share.class.php. The fileUrl parameter can be manipulated to access files without proper authentication, allowing remote attackers to read sensitive files on the server.

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.
-
Confirm KodExplorer installationLocate KodExplorer by searching for index.php or common installation directories (e.g., /var/www/html, /home, C:\inetpub\wwwroot). Look for the kodbox or kodexplorer directory structure.Affected if KodExplorer is present on the server.
-
Determine installed versionCheck the version file or header. Common locations: VERSION file in the root directory, or view the source of index.php for a version string. Compare against affected range: versions up to and including 4.52.Affected if Installed version is 4.52 or lower.
-
Verify vulnerable file existsConfirm /app/controller/share.class.php exists in the installation directory. This is the file containing the vulnerable fileGet function.Affected if share.class.php exists in the /app/controller/ directory.
-
Check share functionality statusInspect the application configuration or database to determine if the share feature is enabled. Look for settings related to 'share' or 'file sharing' in config files (e.g., config.php, config.json).Affected if Share functionality is enabled in the application.
-
Test unauthenticated access to fileUrl parameterSend a crafted HTTP GET request to the share endpoint (typically /?/share/fileGet or /index.php?controller=share&action=fileGet) with a manipulated fileUrl parameter such as ../../../../etc/passwd or ../../config.php. No authentication should be required for the test.Affected if The server returns file contents from outside the intended directory without requiring authentication.
A user is affected if KodExplorer version 4.52 or lower is installed, the share.class.php file exists, and the share feature is enabled, allowing unauthenticated path traversal via the fileUrl parameter.

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 dataImplement proper authentication checks and input validation/sanitization for the fileUrl parameter in the fileGet function. Restrict file access to authorized paths only and validate that requested files fall within allowed directories.
