 "title": "Icegram Express <= 5.9.42 - Authenticated (Contributor+) Insecure Direct Object Reference to Private Post Disclosure via Template Duplication",
 "description": "The Email Subscribers & Newsletters by Icegram Express plugin for WordPress is vulnerable to Insecure Direct Object Reference via the 'duplicate-template' template action in all versions up to, and including, 5.9.42, due to the duplicate_template() handler accepting a user-controlled 'template_id' without checking the post type, the post status, or whether the user may edit that post. This makes it possible for authenticated attackers with Contributor-level access and above to copy any post, including private or password-protected posts written by other users, into a new draft they own, then read its content and custom fields.",
