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 WordPress plugin 'Display Eventbrite Events' allows unauthenticated or unauthorized users to access or manipulate Eventbrite event data due to incorrectly configured access control security levels in the widget-for-eventbrite-api component.

MitigationUpdate the Display Eventbrite Events plugin to the latest version which should include proper authorization checks, or manually implement role-based access control (RBAC) and capability checks on all sensitive API endpoints within the plugin.

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 plugin is installed
    Check your WordPress installation for the Display Eventbrite Events plugin by viewing the Plugins page in wp-admin or inspecting the wp-content/plugins directory for a folder related to display-eventbrite-events.
    Affected if Plugin is not present - not affected
  2. Check installed version
    In WordPress admin, go to Plugins > Installed Plugins and locate Display Eventbrite Events. Note the version number shown and compare it to 6.5.6.
    Affected if Version is 6.5.6 or lower - potentially affected
  3. Identify exposed functionality
    Review the plugin for publicly accessible endpoints, AJAX actions, or admin pages that may be reachable without authentication. Check plugin files for action hooks like wp_ajax or REST API registrations.
    Affected if Plugin exposes admin or privileged functionality to unauthenticated users
  4. Test authorization controls
    If the plugin provides public-facing event display or registration features, attempt to access or modify settings or data that should require admin privileges, without logging in.
    Affected if Unauthenticated access to privileged functions is possible

Environment is affected if the Display Eventbrite Events plugin is installed with version 6.5.6 or lower and exposes functionality without proper authorization checks.
