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 BuddhaThemes ColorFolio - Freelance Designer WordPress Theme allows Object Injection.This issue affects ColorFolio - Freelance Designer WordPress Theme: from n/a through 1.3.

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

The ColorFolio WordPress theme from BuddhaThemes contains a PHP Object Injection vulnerability due to unsafe deserialization of untrusted data. This allows attackers to potentially execute arbitrary code or perform other malicious operations by injecting serialized PHP objects into vulnerable input paths within the theme.

MitigationReplace any unsafe unserialize() calls in the theme with json_decode() or WordPress's built-in sanitization functions, and implement proper input validation on all user-supplied data before deserialization.

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 ColorFolio theme is installed
    Navigate to wp-content/themes/ directory and check for a folder named 'colorfolio' or 'ColorFolio'. Alternatively, in WordPress admin go to Appearance > Themes to list installed themes.
    Affected if The ColorFolio theme folder exists in the WordPress themes directory.
  2. Identify the installed theme version
    Open the style.css file located in the ColorFolio theme folder (wp-content/themes/colorfolio/style.css) and look for the 'Version:' header in the file comments.
    Affected if The version field shows 1.3 or any version where the theme is unmaintained and contains the vulnerable unserialize() call.
  3. Locate the vulnerable unserialize() call
    Search the theme's PHP files for 'unserialize' using grep: grep -r "unserialize" wp-content/themes/colorfolio/ or manually inspect files that handle user input (e.g., AJAX handlers, shortcodes, widget files).
    Affected if Any PHP file in the theme contains an unserialize() call that processes data from $_GET, $_POST, $_REQUEST, or database fields.
  4. Determine if user input reaches the vulnerable code
    Trace the data flow from the unserialize() call backward: check if the deserialized data originates from user-controllable sources like URL parameters, form submissions, or stored database values that could be manipulated by an attacker.
    Affected if User-supplied input (directly or indirectly) can reach the unserialize() function without validation.

You are affected if the ColorFolio theme is installed, contains an unserialize() call on user-controlled data, and the theme version is 1.3 or unpatched.
