url/wp-content/uploads/contest-gallery/gallery-id-{{path}}/json/image-comments/image-comments-{{path}}.json
path/wp-content/uploads/contest-gallery/gallery-id-*/json/image-comments/image-comments-*.json
  • Unauthenticated GET requests to the Contest Gallery image-comments JSON endpoint expose sensitive data. Look for HTTP 200 responses containing both 'WpUserId":' and 'userIP":' fields in the JSON body.
  • The vulnerable endpoint returns application/json content-type; monitor for unauthenticated access to paths matching /wp-content/uploads/contest-gallery/gallery-id-<number>/json/image-comments/image-comments-<number>.json.
  • Exploit requires no authentication and no special conditions (PR:N, UI:N, AC:L). Any unauthenticated HTTP GET to the image-comments JSON path on an affected WordPress site is sufficient to trigger information disclosure.
  • ·The vulnerable path uses a numeric gallery ID as the variable component; the Nuclei template brute-forces this with a numbers wordlist. Detection coverage depends on enumerating valid gallery IDs.
  • ·Affected versions are Contest Gallery n/a through 23.1.2; the plugin must be installed and have at least one gallery with comments for the endpoint to return data.
