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
Missing Authorization vulnerability in Anton Shevchuk Constructor allows Accessing Functionality Not Properly Constrained by ACLs. This issue affects Constructor: from n/a through 1.6.5.

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 Constructor component in Anton Shevchuk has a missing authorization vulnerability where certain functionality is not properly constrained by Access Control Lists (ACLs). This allows unauthorized users to access functions that should require elevated privileges, likely due to missing or insufficient permission checks before executing sensitive operations.

MitigationUpgrade Constructor to version 1.6.6 or later which contains the authorization fix. If immediate upgrade is not possible, review and restrict access to the Constructor component functions through web server configuration or temporary ACL modifications.

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 Anton Shevchuk Constructor plugin files
    Check the WordPress plugins directory at wp-content/plugins/ for a folder named 'constructor' or similar naming convention used by Anton Shevchuk. Alternatively, query the WordPress database table wp_options for option_name='active_plugins' to see if the plugin is enabled.
    Affected if The plugin folder exists in the plugins directory or the plugin is listed in active_plugins
  2. Identify the installed plugin version
    Open the main plugin PHP file (usually constructor.php or index.php inside the plugin folder) and locate the version comment or constant at the top of the file. Compare this version against the known affected version range for CVE-2025-53302.
    Affected if The installed version falls within the affected version range for this CVE
  3. Verify if administrative functions are accessible without authentication
    Use a tool like curl or Burp Suite to send requests to common WordPress admin AJAX endpoints (wp-admin/admin-ajax.php) or direct plugin PHP files without providing authentication cookies or credentials. Check if the plugin responds with expected functionality rather than returning a 401 Unauthorized or redirecting to the login page.
    Affected if The plugin returns functional responses to unauthenticated requests that should require administrative privileges
  4. Inspect plugin source code for missing capability checks
    Review the main plugin PHP files for function definitions that handle user actions (such as save, update, delete, or export operations). Search for calls to functions like current_user_can(), check_admin_referer(), or wp_verify_nonce(). If these authorization checks are missing before sensitive operations, the vulnerability is present.
    Affected if Sensitive functions lack proper current_user_can() or nonce verification checks

The environment is affected if the Anton Shevchuk Constructor plugin is installed, the installed version is within the affected range, and the plugin exposes administrative functions without requiring authentication or proper capability verification.
