CVE-2026-93366Network attack vectorHinoki check available

Cross-account media deletion via unchecked page UUID

Published Sep 25, 2026 · Updated Sep 25, 2026

Authorization bypass in Bludit CMS 3.22.0 and earlier and 4.0.0-beta-1 allows remote authenticated users to delete other users' media. The content-get-list endpoint exposes page UUIDs, while list-images and delete-image trust an arbitrary uuid to select another page's media directory without enforcing ownership. Author-role access and IMAGE_RESTRICT are required; exploitation discloses filenames and permanently removes media from pages owned by other users, including administrators.
