 "title": "Meow Gallery <= 5.6.1 - Authenticated (Contributor+) Sensitive Information Exposure via Gallery Shortcode",
 "description": "The Meow Gallery plugin for WordPress is vulnerable to Sensitive Information Exposure via the 'posts' attribute of the [meow-gallery] / [gallery] shortcode in all versions up to, and including, 5.6.1 due to missing checks on the status, visibility and password protection of the posts whose titles and excerpts are added to the gallery data printed in the page. This makes it possible for authenticated attackers, with contributor-level access and above, to embed the shortcode with arbitrary post IDs and read the titles and excerpts of draft, pending, private and password-protected posts they should not have access to.",
