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 Five Star Restaurant Reservations WordPress plugin allows attackers to exploit incorrectly configured access control security levels, enabling unauthorized users to perform actions they should not have privileges for.

MitigationImplement proper capability checks and authorization validation on all sensitive plugin functions and AJAX endpoints to enforce correct access control levels.

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
    Check your WordPress installation for the Five Star Restaurant Reservations plugin in wp-content/plugins/ or via WordPress admin dashboard under Plugins
    Affected if Plugin is installed and active
  2. Identify installed version
    Locate the plugin's main PHP file (typically restaurant-reservations.php) and read the version header comment, or check the version in WordPress admin plugin list
    Affected if Version is older than the patched release and matches publicly disclosed affected versions
  3. Verify AJAX endpoint exposure
    Inspect the plugin's includes/ajax.php or similar AJAX handler files to see if capability checks are properly implemented before processing requests
    Affected if AJAX endpoints lack proper capability checks or use insufficient access control validation
  4. Test authorization on sensitive functions
    Use a low-privilege user account (subscriber or contributor role) to attempt actions like managing reservations, modifying settings, or accessing admin functions that should require administrator privileges
    Affected if Low-privilege users can perform actions reserved for administrators
  5. Review user role configuration
    Check the plugin settings under Reservations > Settings > General to see if Access Control or Permission settings allow overly broad user roles to access restricted features
    Affected if Plugin configuration grants excessive permissions to non-administrator roles

Your environment is affected if the Five Star Restaurant Reservations plugin is installed with a version that matches the affected range AND unauthorized users can access administrative functions or perform privileged actions due to missing capability checks.

Generated from the published advisory. Verify against your own configuration.
