CVE-2026-7044
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 found in GreenCMS up to 2.3. Affected is the function themeadd of the file /index.php?m=admin&c=custom&a=themeadd. The manipulation results in unrestricted upload. The attack can be launched remotely. The exploit has been made public and could be used. This vulnerability only affects products that are no longer supported by the maintainer.
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 confidenceUnrestricted file upload vulnerability in GreenCMS admin panel's themeadd function at /index.php?m=admin&c=custom&a=themeadd allows remote attackers to upload arbitrary files (likely web shells) without proper validation, potentially achieving remote code execution.

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 GreenCMS installationLook for GreenCMS files on the web server, typically in the web root directory. Check for the presence of index.php and /admin/ directory structure.Affected if GreenCMS files are found on the server
-
Identify GreenCMS versionCheck the version.php file in the GreenCMS root directory, or log into the admin panel and look for version information typically displayed in the footer or admin settings.Affected if Installed version is 2.3 or earlier (based on the fact that 2.3 is mentioned as no longer supported)
-
Verify admin panel accessibilityAttempt to access the admin login page at /index.php?m=admin or check server access logs for requests to admin endpoints.Affected if The admin panel is accessible without proper network restrictions
-
Check if vulnerable themeadd endpoint existsVerify the file /index.php exists and contains the custom controller handling, then check if the themeadd action is defined in the custom controller file.Affected if The themeadd function exists and is accessible to authenticated admin users
-
Inspect file upload configurationReview the themeadd function code in the admin/custom.php or equivalent controller file to confirm no file type validation is performed on uploaded files.Affected if No file type or extension validation is performed on uploads through this endpoint
A user is affected if GreenCMS version 2.3 or earlier is installed and the admin panel with the themeadd functionality is accessible.

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 dataSince GreenCMS 2.3 is no longer supported, disable or restrict access to the admin panel themeadd functionality; implement web-based access controls to prevent unauthorized admin access; consider deploying a WAF rule to block malicious file uploads to this endpoint.
