Technical summary

The Photo Engine (Media Organizer & Lightroom) plugin for WordPress is vulnerable to authorization bypass due to improper verification of user authorization. This allows unauthenticated attackers to delete arbitrary media attachments and upload new attachments. The vulnerability is caused by the plugin not properly verifying that a user is authorized to perform an action.
