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 Five Star Restaurant Reservations plugin allows unauthenticated or unauthorized users to access sensitive functionality or data due to incorrectly configured access control. The vulnerability enables attackers to bypass proper authentication/authorization checks, likely exposing reservation management, customer data, or administrative functions that should be restricted.

MitigationImplement proper role-based access control (RBAC) checks on all sensitive endpoints and functions, enforce authorization validation for every request accessing restricted resources, and audit existing code for similar access control flaws.

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 plugin installation
    Navigate to WordPress admin dashboard > Plugins and verify 'Five Star Restaurant Reservations' is installed and active
    Affected if Plugin is installed and active in WordPress
  2. Identify installed version
    In Plugins list, click on the plugin to view details, or check the plugin's main PHP file header in wp-content/plugins/five-star-restaurant-reservations/ for the 'Version' field
    Affected if Version matches or falls within any affected version range (compare against CVE reference)
  3. Test unauthenticated access to reservation functions
    Submit a reservation request without authentication or with a low-privilege user account (subscriber role) to test if actions like modifying reservations, accessing admin-only data, or bypassing role restrictions succeed
    Affected if Unauthenticated or low-privilege users can perform admin-level actions such as deleting reservations, accessing all bookings, or modifying settings
  4. Verify authorization checks on admin endpoints
    Use a browser or HTTP tool to access plugin admin URLs (such as reservation management pages) while logged out or as a subscriber-level user; observe if access is granted without proper role verification
    Affected if Access is granted to admin-only pages without proper authentication or authorization validation
  5. Inspect server logs for unauthorized access attempts
    Review web server access logs and WordPress debug logs for repeated requests to plugin endpoints from unauthenticated or low-privilege IPs that result in successful state changes
    Affected if Logs show successful privileged actions from unauthenticated or role-restricted users

Environment is affected if the Five Star Restaurant Reservations plugin is installed, the installed version falls within the affected range, and unauthenticated or low-privilege users can access or modify reservation data intended for administrators.
