NextGEN Gallery < 4.5.0 - Contributor+ Image Metadata Disclosure via IDOR

Description

The plugin does not verify that the requesting user is entitled to a given image record before returning it, allowing users with the Contributor role and above to read the stored metadata of any image on the site, including images in galleries belonging to other users. The disclosed data includes the image's stored EXIF subset, covering camera make and model and capture timestamp, along with internal checksums and identifiers that the plugin's own capability-gated read path reserves to administrators.
