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 awethemes Hillter allows Object Injection. This issue affects Hillter: from n/a through 3.0.7.

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 the Hillter theme from awethemes, where untrusted data is deserialized using PHP's unserialize() function without proper validation. Object injection can allow attackers to manipulate PHP objects during deserialization, potentially leading to code execution or other attacks depending on available 'gadget chains' in the application or installed plugins.

MitigationUpdate Hillter to the latest patched version immediately. If no update is available, disable the theme and consider removing it from the WordPress installation until a fix is released.

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 Hillter theme version
    Navigate to WordPress dashboard > Appearance > Themes and locate the Hillter theme. Click on the theme to view its details, or inspect the style.css file in wp-content/themes/hillter/ to find the Version header.
    Affected if The installed version is unknown, unpatched, or cannot be verified against a fixed version.
  2. Locate vulnerable unserialize() call
    Search the Hillter theme files for 'unserialize' using grep or a file search: grep -r "unserialize" wp-content/themes/hillter/
    Affected if The theme contains any unserialize() call that processes user-supplied data without validation.
  3. Inspect the unserialize data source
    Examine the file containing the unserialize() call. Identify what variable or input is being passed to it (e.g., $_GET, $_POST, $_COOKIE, or a database field).
    Affected if User-controllable data such as request parameters or stored database values flow directly into the unserialize() function.
  4. Check for registered magic methods
    Search the Hillter theme and active plugins for magic method definitions: grep -rE "__destruct|__wakeup|__toString|__get|__set|__call" wp-content/themes/hillter/ and wp-content/plugins/
    Affected if Any class with magic methods that could be triggered during deserialization is autoloaded by the theme or active plugins.

You are affected if the Hillter theme contains an unserialize() call that processes unauthenticated user input and vulnerable magic methods exist in the theme or loaded plugins.
