Classified Listing lets Contributors read private content
Classified Listing before 5.4.4 exposes an AJAX action that returns post content without checking capability or ownership. A Contributor-or-higher user can supply an arbitrary post identifier and read posts, pages and custom post types belonging to other users, including draft, pending and private content. The CNA record does not disclose the action, identifier parameter or callback.

This CVE was published Aug 03, 2026 and is one of 27 known issues for this plugin.
Update, patch or deactivate.
Update Classified Listing to 5.4.4 or later. Review AJAX activity by delegated authors and treat sensitive draft or private content as potentially exposed.
A safe version is available, so updating to that version or later is the preferred remediation. If an immediate update is not practical, consider a targeted application patch or temporarily restricting the affected functionality.
Deactivate only when warranted by your risk profile, or when advised by your hosting provider in the limited circumstances where the vulnerability cannot otherwise be mitigated. If you’re unsure which action is appropriate, contact Fused or your hosting provider for guidance.
Technical 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.
