## Affected

- Unknown Classified Listing: fixed in 5.4.4

## Description

The Classified Listing WordPress plugin before 5.4.4 does not perform a capability or ownership check on an AJAX action that returns a post's content, allowing users with contributor-level access and above to read the content of any post, page, or custom post type on the site — including drafts, pending, and private posts owned by other users — regardless of ownership.

## What to do
