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 · unedited
Unauthenticated PHP Object Injection in Manufaktur Solutions <= 1.1.1 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 confidence

Unauthenticated PHP Object Injection in Manufaktur Solutions <= 1.1.1 allows remote attackers to inject malicious PHP objects via untrusted input deserialization, potentially leading to remote code execution.

MitigationUpgrade to a patched version; if unavailable, implement strict input validation and avoid using unserialize() on user-controlled data, replacing with json_decode() or safe deserialization libraries.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify Manufaktur Solutions installation and version
    Locate the application's main PHP files (index.php, bootstrap files, or composer.json) and check the version number defined in the code, configuration files, or changelog. Common paths include the web root or a vendor directory.
    Affected if The installed version is 1.1.1 or lower, or the version cannot be determined but the software is Manufaktur Solutions.
  2. Search for unserialize() calls handling user input
    Grep the application source code for 'unserialize(' patterns, then inspect each occurrence to determine if the input source is $_GET, $_POST, $_REQUEST, or other user-controllable variables.
    Affected if Code uses unserialize() on data derived from $_GET, $_POST, $_REQUEST, or similar superglobals without prior sanitization.
  3. Identify input entry points feeding deserialization
    Review PHP files in the application's entry points (index.php, api endpoints, controllers) to trace which parameters reach the unserialize() function.
    Affected if User-supplied parameters from HTTP requests are passed directly to unserialize() without validation.
  4. Check for known magic methods usable as gadget chains
    Search the codebase for PHP classes with __destruct(), __wakeup(), or __invoke() magic methods that could be chained with the injection point.
    Affected if The application contains magic methods in its classes that could be triggered by injected PHP objects.

The environment is affected if Manufaktur Solutions version 1.1.1 or lower is installed AND the application uses unserialize() on untrusted user-controlled input from HTTP requests.

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.
