GHSA-W939-C8QP-6HM2

Vulnerability from github – Published: 2026-07-16 06:31 – Updated: 2026-07-16 06:31

Details

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.

Severity

4.3 (Medium)
