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
Subscriber Broken Access Control in Motors < 1.4.107 versions.

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

Broken Access Control vulnerability in Motors plugin/theme versions below 1.4.107 allows authenticated users with the low-privilege 'subscriber' role to access functionality or data that should be restricted to higher-privileged users. This is a vertical privilege escalation issue where subscriber-level accounts can perform actions beyond their intended limited permissions.

MitigationUpgrade Motors to version 1.4.107 or later to obtain the access control fix. Verify that subscriber accounts can no longer access restricted functionality after updating.

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. Determine Motors version
    Locate the installed Motors theme/plugin version in your WordPress admin dashboard under Appearance > Themes (for themes) or Plugins (for plugins), or check the version declaration in the theme's style.css or plugin header
    Affected if The installed version is below 1.4.107
  2. Verify subscriber role exists
    In WordPress admin, navigate to Users > Users List and filter or check for accounts assigned the 'subscriber' role, or inspect user roles via database or user management tools
    Affected if Any user accounts with the 'subscriber' role exist in the system
  3. Confirm subscriber access scope
    Review what capabilities or access points the subscriber role has been granted within the Motors theme configuration - check role settings, permission panels, or access control menus if available in the theme settings
    Affected if Subscriber role has been granted access to functionality typically reserved for higher-privileged roles (such as dealer accounts, listing management, or admin-level features)
  4. Cross-reference version against affected range
    Compare your confirmed Motors version to the affected range: any version below 1.4.107 is considered vulnerable
    Affected if Installed version is below 1.4.107 and subscriber users exist with elevated access capabilities

Your environment is affected if Motors version is below 1.4.107 and subscriber-level accounts exist with access to functionality that should be restricted to higher-privileged roles.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.

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

Upgrade Motors to version 1.4.107 or later to obtain the access control fix. Verify that subscriber accounts can no longer access restricted functionality after updating.

Recommended fix High confidence

Motors 1.4.107 (or latest available version)

  1. Create a full backup of your site files and database.
  2. Update the Motors theme/plugin to version 1.4.107 or later (e.g., via WordPress admin dashboard, theme installer, or package manager).
  3. Confirm the new version is installed (check the version number in the theme/plugin settings).
  4. Test the subscriber role to ensure the broken access control is mitigated (e.g., verify they cannot access admin‑only pages).
  5. Deploy the updated site to production after successful testing.
Caveat Review the Motors release notes for any breaking changes before upgrading.
