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 themeton Consult Aid consultaid allows Object Injection.This issue affects Consult Aid: from n/a through <= 1.4.3.

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

This is a PHP Object Injection vulnerability in themeton Consult Aid. The application deserializes untrusted data without proper validation, allowing attackers to inject malicious PHP objects. Successful exploitation can lead to remote code execution, file operations, or sensitive data disclosure depending on available gadget chains in the application and related libraries.

MitigationUpgrade to the latest version of Consult Aid when a patched release becomes available. If no patch is available, audit the codebase for deserialization functions (unserialize()) and replace with safe alternatives like JSON encoding/decoding, or implement strict allowlist validation for any unserialize() calls.

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. Confirm Consult Aid plugin is installed
    Navigate to WordPress admin > Plugins and look for 'Consult Aid' in the list of installed plugins, or check the /wp-content/plugins/ directory for a consult-aid folder
    Affected if The plugin is present in the installation
  2. Determine installed Consult Aid version
    In WordPress admin > Plugins, click on the Consult Aid plugin to view its version number, or read the main plugin PHP file header for the Version field
    Affected if The version cannot be determined or is earlier than the patched release
  3. Identify plugin endpoints accessible remotely
    Check for plugin AJAX endpoints (usually /wp-admin/admin-ajax.php?action=...) or REST API routes registered by Consult Aid, or review the plugin's PHP files for $_POST/$_GET/$_REQUEST data passed to unserialize()
    Affected if The plugin processes serialized data from unauthenticated requests
  4. Inspect for unserialize() usage on user input
    Search plugin source code (if accessible via FTP or file manager) for patterns like unserialize($_POST[...]), unserialize($_REQUEST[...]), or unserialize($_GET[...]) without prior sanitization
    Affected if Unsafe deserialization calls exist and accept external input
  5. Review access controls on plugin functionality
    Test plugin endpoints without authentication by sending a request with no valid WordPress nonce or session cookie
    Affected if Plugin functionality is reachable without authentication

The environment is affected if the Consult Aid plugin is installed, processes untrusted serialized data, and is accessible without authentication.

Mitigation

Upgrade to the latest version of Consult Aid when a patched release becomes available. If no patch is available, audit the codebase for deserialization functions (unserialize()) and replace with safe alternatives like JSON encoding/decoding, or implement strict allowlist validation for any unserialize() calls.
