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. Locate the installed Booking Activities plugin version
    In WordPress admin, go to Plugins > Installed Plugins > find Booking Activities and read the version number displayed below the plugin name. Alternatively, check the main plugin file (usually booking-activities/booking-activities.php) for the 'Version' header comment.
    Affected if version displayed is 1.16.48.1 or lower (any version below 1.16.48.1)

The site is affected if the Booking Activities plugin version is 1.16.48.1 or below, since the flaw is unauthenticated and requires no special configuration to be exploitable.
