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 · high confidence

This is a PHP Object Injection vulnerability caused by deserializing untrusted data in the BoldThemes Goldenblatt WordPress theme. The vulnerability allows attackers to inject malicious PHP objects, potentially leading to remote code execution (RCE) via object injection attacks such as deserialization gadget chains.

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. Locate the Goldenblatt theme directory
    Check your WordPress installation's wp-content/themes/ directory for a folder named 'goldenblatt' or similar BoldThemes Goldenblatt theme folder
    Affected if The Goldenblatt theme folder exists in the themes directory
  2. Identify the installed theme version
    Open the theme's style.css file (typically at wp-content/themes/goldenblatt/style.css) and look for the 'Version:' declaration in the file header comment
    Affected if The version number found is below 1.3.0 (e.g., 1.2.9, 1.2.8, etc.)
  3. Check for vulnerable deserialization code
    Search within the theme folder (particularly in PHP files) for calls to unserialize() function that process user-controlled or external input without validation
    Affected if Code containing unserialize() on untrusted data is present and the theme version is below 1.3.0
  4. Review theme AJAX endpoints and hooks
    Inspect the theme's functions.php and any ajax-related PHP files for deserialization operations triggered by WordPress actions or AJAX calls
    Affected if AJAX or action hooks that trigger unsafe unserialize() calls exist and the theme version is below 1.3.0

You are affected if the BoldThemes Goldenblatt theme is installed with a version lower than 1.3.0 and contains vulnerable unserialize() code handling untrusted input.
