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 Missing Authorization (Broken Access Control) vulnerability in the Nexcess Event Tickets WordPress plugin. The vulnerability allows unauthenticated or unauthorized users to access functionality or data that should require proper access control checks. With a CVSS score of 7.5 (HIGH), the issue stems from incorrectly configured access control security levels in the plugin, likely meaning certain sensitive endpoints or actions lack proper capability checks or role-based access validation.

MitigationUpdate the Event Tickets plugin to the latest patched version once available. If no update exists, review and implement proper authorization checks on all sensitive functions, or temporarily restrict access at the server level (e.g., via .htaccess or firewall rules) until a patch 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. Verify Nexcess Event Tickets plugin is installed
    Log in to WordPress admin and navigate to Plugins > Installed Plugins, or inspect the wp-content/plugins/ directory for a folder named 'event-tickets', 'nexcess-event-tickets', or similar.
    Affected if The plugin is present in the WordPress installation.
  2. Identify the installed plugin version
    In WordPress admin, find the plugin in the Plugins list and view the version number displayed beneath the plugin name, or open the main plugin PHP file and look for the 'Version' header in the plugin comment block.
    Affected if The version matches any known affected version range for CVE-2026-57705.
  3. Locate plugin endpoints and AJAX actions
    Search the plugin directory for files containing 'add_action' or 'add_shortcode' calls, particularly those registering REST API routes, admin-ajax.php handlers, or front-end submission forms.
    Affected if The plugin exposes public-facing endpoints or AJAX actions without explicit capability checks.
  4. Inspect access control implementation
    Open the main plugin PHP files and search for 'current_user_can', 'capability', ' Roles', or 'permission' to verify whether sensitive functions include proper authorization checks.
    Affected if Sensitive functions lack current_user_can() calls or role-based validation.
  5. Test unauthorized access to sensitive features
    Using a tool like Burp Suite or curl, attempt to access plugin features (such as ticket viewing, event management, or data export) without authenticating or with a low-privilege user account.
    Affected if Unauthenticated or low-privilege users can access functionality that should require higher privileges.

Your environment is affected if the Nexcess Event Tickets plugin is installed, lacks proper capability checks on its endpoints, and allows unauthenticated or unauthorized access to sensitive functionality.
