What the vulnerability does

01Description

The List category posts plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 0.95.0 via the sanitize_status. This makes it possible for authenticated attackers, with contributor-level access and above, to extract titles, full content, excerpts, dates, authors, and custom-field metadata of other users' pending-review, scheduled, and trashed posts by embedding a crafted [catlist] shortcode in their own draft and previewing it. This vulnerability is a bypass of the incomplete fix introduced for CVE-2025-11377 in version 0.93.0.

Explanation of Vulnerability in Simple Terms

02Summary

List category posts versions up to 0.95.0 lack proper authorization checks, allowing authenticated users to view data they should not have access to. An attacker with a low-privilege account can read sensitive information by making direct requests to the plugin. The vulnerability affects confidentiality but not data integrity or availability. Update to a version newer than 0.95.0.
