 "description": "The Meow Lightbox plugin for WordPress is vulnerable to Sensitive Information Exposure via the public 'meow-lightbox/v1/regenerate_mwl_data' REST API endpoint in all versions up to, and including, 5.6.3, due to a missing check on whether the requested attachment may be viewed by the requester. This makes it possible for unauthenticated attackers to retrieve the title, caption, description, alt text, author, file and download URLs and EXIF metadata, including GPS coordinates, of arbitrary attachments by ID, including images attached to private or draft posts.",
