CVE-2026-51924
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 · uneditedAn issue in docuForm GmbH Client v.11.11c allows a remote attacker to execute arbitrary code via the file upload and report.php component
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 docuForm GmbH Client v.11.11c contains a file upload vulnerability in the report.php component that allows remote attackers to upload malicious files and execute arbitrary code on the underlying system.

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 installed docuForm versionLocate the docuForm installation directory and check version files, typically found in the application root or an 'about' page. Compare the version string to 11.11c.Affected if The installed version matches exactly 11.11c or falls within the affected version range.
-
Locate report.php componentSearch the web server document root for the file 'report.php' using file system search or by checking common paths like /report.php, /components/report.php, or /modules/report.php.Affected if The report.php file exists in the web-accessible directory structure.
-
Verify upload functionality exposureAttempt to access the report.php page via HTTP/HTTPS without credentials, or check the web server access logs for requests to report.php that include multipart form data or file upload parameters.Affected if The report.php upload endpoint is reachable without authentication.
-
Check upload directory web accessibilityExamine the web server configuration and the report.php source code to determine where uploaded files are stored. Verify that this directory is within the web root and serves files with their original extensions.Affected if Uploaded files are stored in a web-accessible directory and served with executable extensions (e.g., .php, .phtml).
-
Confirm script execution is enabled in upload pathReview the web server configuration (Apache .htaccess, nginx config, or IIS handler mappings) for the upload directory. Check if script execution restrictions are in place.Affected if The upload directory allows execution of server-side scripts (PHP, etc.) or has no restrictions blocking script execution.
A user is affected if they run docuForm GmbH Client v.11.11c with the report.php component exposed and the upload directory configured to allow script execution.

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 strict file type validation using magic bytes rather than extensions, store uploaded files outside the web root with random names, disable script execution in upload directories, and apply principle of least privilege to the web server process.
