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 Brecht Visual Link Preview visual-link-preview allows Exploiting Incorrectly Configured Access Control Security Levels.This issue affects Visual Link Preview: from n/a through <= 2.2.9.

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

Missing Authorization vulnerability in the Visual Link Preview WordPress plugin allows exploiting incorrectly configured access control security levels. The plugin fails to properly validate user capabilities before performing privileged operations, potentially enabling lower-privileged or unauthenticated users to access sensitive functionality.

MitigationImplement proper WordPress capability checks (current_user_can) and nonce verification for all AJAX actions and admin functions. Audit all functions that modify data or access sensitive information to ensure they enforce appropriate authorization controls.

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 installed plugin version
    Navigate to WordPress admin > Plugins > Visual Link Preview and note the version number, or run: wp plugin list --name='visual-link-preview' --format=table
    Affected if The installed version matches the vulnerable version range for this CVE (check against official vulnerability disclosure)
  2. Verify WordPress user role configuration
    In WordPress admin, go to Users > All Users and review the roles assigned to each user account. Note which users have Subscriber, Contributor, or Author roles versus Administrator
    Affected if Lower-privileged users (Subscriber, Contributor, Author) exist on the site and the plugin exposes functionality they should not access
  3. Inspect AJAX action handlers for capability checks
    Locate the plugin PHP files (typically in wp-content/plugins/visual-link-preview/) and search for 'add_action' calls with 'wp_ajax_' hook. Verify if each handler includes 'current_user_can()' or a capability check before processing
    Affected if AJAX handlers exist that lack 'current_user_can()' validation or capability checks before executing privileged operations
  4. Review admin function authorization
    Examine the plugin admin PHP files for functions that modify data or access sensitive information. Check if these functions verify user capabilities using current_user_can() or similar WordPress authorization functions
    Affected if Admin functions that handle sensitive operations are missing proper capability verification checks
  5. Check for nonce verification in AJAX calls
    Search the plugin source code for 'wp_ajax_' actions and verify if each includes nonce verification using 'check_ajax_referer' or 'wp_verify_nonce' before processing requests
    Affected if AJAX actions process requests without validating nonces, allowing potential request forgery
  6. Test unauthenticated access to plugin features
    Attempt to access plugin functionality directly via AJAX endpoints (usually /wp-admin/admin-ajax.php?action=visual_link_preview_*) while logged out or as a low-privilege user
    Affected if Unauthenticated or low-privileged users can successfully execute plugin functions that should require higher privileges

A user is affected if they have Visual Link Preview plugin installed and the installed version is within the vulnerable range, and the plugin code is missing capability checks (current_user_can) and nonce verification on its AJAX actions and admin functions.
