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
Vvveb is a powerful and easy to use CMS with page builder to build websites, blogs or ecommerce stores. Prior to 1.0.8.3, the backend admin/auth-token endpoint allows an authenticated administrator to load another administrator's REST API token list by supplying that user's admin_id. This can disclose sensitive API tokens belonging to other administrators. This vulnerability is fixed in 1.0.8.3.

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 · high confidence

The backend admin/auth-token endpoint in Vvveb CMS prior to 1.0.8.3 allows an authenticated administrator to retrieve another administrator's REST API token list by directly specifying that user's admin_id parameter, resulting in an Insecure Direct Object Reference (IDOR) that exposes sensitive API tokens belonging to other administrators.

MitigationUpgrade to Vvveb 1.0.8.3 or later to obtain the patch, and immediately rotate any API tokens that may have been exposed prior to applying the fix.

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 Vvveb CMS installation
    Identify if the web application is Vvveb CMS by examining the application footer, login page, or checking for Vvveb-specific file structures or cookies
    Affected if The application is running Vvveb CMS
  2. Check Vvveb version
    Locate the installed version number in the administration panel footer, or check version files in the application root directory
    Affected if The version is below 1.0.8.3 (any version prior to 1.0.8.3)
  3. Verify admin user accounts exist
    Access the admin panel and navigate to the user/administrator management section to confirm multiple admin accounts exist
    Affected if There are two or more administrator accounts configured
  4. Check for REST API token configuration
    In the admin panel, locate the API settings or authentication token management area where REST API tokens are generated or stored for administrators
    Affected if The system has REST API tokens enabled or configured for admins
  5. Test IDOR vulnerability on auth-token endpoint
    Using an authenticated admin session, make a direct HTTP request to the /admin/auth-token endpoint with a different admin_id parameter to see if tokens for that other admin are returned without proper authorization
    Affected if The endpoint returns another administrator's API tokens when a different admin_id is supplied

A user is affected if they run Vvveb CMS version below 1.0.8.3 with multiple admin accounts that have REST API tokens configured, where the auth-token endpoint permits unauthorized access to other admins' tokens.

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

Upgrade to Vvveb 1.0.8.3 or later to obtain the patch, and immediately rotate any API tokens that may have been exposed prior to applying the fix.

Recommended fix High confidence

1.0.8.3

  1. Backup the current Vvveb installation and database before proceeding with any upgrade
  2. Download Vvveb version 1.0.8.3 from the official Vvveb repository on GitHub
  3. Follow the standard Vvveb upgrade procedure to apply version 1.0.8.3
  4. Verify that the upgrade was successful by logging into the admin dashboard
  5. Test that the admin/auth-token endpoint properly enforces authorization and no longer allows accessing other administrators' API tokens
