## Description

The VK Filter Search plugin for WordPress is vulnerable to Sensitive Information Exposure via the call-filter-search block in all versions up to, and including, 2.20.7. This is due to the block's render callback outputting the post_content of any supplied post ID without checking the post's type, status or password protection. This makes it possible for authenticated attackers, with contributor-level access and above, to read the contents of draft, private and password-protected posts they should not have access to.
