CVE-2026-15530Public exploitNetwork attack vector

Attachment disclosure via unauthenticated action dispatch

Published Jul 13, 2026 · Updated Jul 13, 2026

Missing authorization in WuzhiCMS 4.1.0 and earlier allows remote attackers to enumerate uploaded attachments through its Attachment API. The upload action dispatcher in coreframe/app/attachment/index.php serves config and listimage requests without establishing a member or administrator session. No authentication, cookie, or user interaction is required, and responses expose attachment URLs, filenames, counts, and editor configuration.
