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
Deserialization of Untrusted Data vulnerability in Themify Themify Edmin allows Object Injection.This issue affects Themify Edmin: from n/a through 2.0.0.

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

A deserialization vulnerability in Themify Edmin (versions up to 2.0.0) allows unauthenticated attackers to inject malicious PHP objects by supplying untrusted serialized data. This PHP object injection can potentially lead to remote code execution if vulnerable gadgets exist in the application or loaded libraries.

MitigationUpdate Themify Edmin to the latest patched version once available; alternatively, disable the affected theme until a fix is released. If immediate remediation is required, audit and remove insecure deserialization of user-supplied data.

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. Verify Themify Edmin theme is installed
    Check your WordPress themes directory for the Themify Edmin theme folder. In a typical WordPress installation, this would be at /wp-content/themes/themify-edmin/
    Affected if The Themify Edmin theme folder exists in the themes directory
  2. Confirm the installed version
    Look for a version file or theme header within the Themify Edmin theme folder. Common locations include style.css header comments, version.php, or a config.json file. Compare the version number to the affected range (2.0.0 and below)
    Affected if The detected version is 2.0.0 or any version below 2.0.0
  3. Identify deserialization sinks in the theme
    Search the Themify Edmin theme folder for PHP files containing the unserialize() function. Use a command like 'grep -r "unserialize" /path/to/themify-edmin/' to locate potential deserialization points
    Affected if Any PHP file in the theme uses unserialize() on data that could be influenced by user input
  4. Check if user input reaches deserialization
    Examine the identified deserialization code paths to determine whether $_GET, $_POST, $_COOKIE, or similar user-supplied data is passed to unserialize() without validation
    Affected if User-controlled data is directly passed to unserialize() without sanitization

You are affected if Themify Edmin version 2.0.0 or below is installed and the theme contains code that deserializes untrusted user-supplied data.
