CVE-2026-33887Network attack vector

Authenticated revision disclosure via missing collection authorization

Published Mar 27, 2026 · Updated Mar 27, 2026

Missing authorization in Statamic CMS before 5.73.16 and 6.0.0-alpha.1 through 6.7.1 allows remote authenticated users to read entry revisions. Its revision controllers return entry field values and blueprint data, and accept revision-creation requests, without enforcing the collection permission checks used by the main entry controllers. Control Panel access and a collection with revisions enabled are required; creation only snapshots existing content and does not change published content.
