Deserialization of Untrusted Data vulnerability in BoldThemes DentiCare denticare allows Object Injection.This issue affects DentiCare: 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

A deserialization of untrusted data vulnerability in the BoldThemes DentiCare WordPress theme allows remote attackers to inject PHP objects, potentially leading to remote code execution. This affects versions prior to 1.4.3.

MitigationUpdate the DentiCare theme to version 1.4.3 or later to patch the deserialization vulnerability. If the site uses custom child theme modifications, test thoroughly after update.

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 if DentiCare theme is installed
    Check the wp-content/themes directory for the denticar theme folder, or view the installed themes in WordPress admin under Appearance > Themes
    Affected if The DentiCare theme folder exists in the WordPress themes directory
  2. Determine the installed DentiCare version
    Open the theme's style.css file in wp-content/themes/denticar/ and locate the 'Version:' header in the file comments at the top
    Affected if The version listed is lower than 1.4.3 (for example, 1.4.2, 1.4.1, 1.0, etc.)
  3. Check for PHP deserialization functions receiving user input
    Search the theme files (particularly in the root and includes subdirectories) for patterns like unserialize(unserialize($_POST, unserialize($_GET, or unserialize($_REQUEST. Also look for any AJAX or wp_ajax hooks that process serialized data
    Affected if The theme contains code that passes user-supplied input (POST, GET, REQUEST parameters) directly to PHP unserialize() function

The environment is affected if the DentiCare theme version is prior to 1.4.3 AND the theme contains vulnerable deserialization code that processes untrusted input.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Update the DentiCare theme to version 1.4.3 or later to patch the deserialization vulnerability. If the site uses custom child theme modifications, test thoroughly after update.

Recommended fix High confidence

1.4.3

  1. 1. Log in to the WordPress admin dashboard
  2. 2. Navigate to Appearance > Themes
  3. 3. Locate the DentiCare theme
  4. 4. Check the current version to confirm it's below 1.4.3
  5. 5. Update the theme to version 1.4.3 or later through the WordPress theme manager, or download the latest version from the theme provider and upload it
