PostX Gutenberg Blocks Saved Templates Addon < 2.4.10 - Private Content Disclosure

Description

The plugin, with Saved Templates Addon enabled, allows users with Contributor roles or higher to read password-protected or private post contents the user is otherwise unable to read, given the post ID.

Proof of Concept

If the post 1234, created by other users, is set as private, save [gutenberg_post_blocks id="1234"] and preview. The private post's contents will be displayed.
