CVE-2026-54005Network attack vector

Authenticated page disclosure via missing access check

Published Jul 9, 2026 · Updated Jul 9, 2026

Missing authorization in Kirby before 4.9.4 and 5.0.0 through 5.4.3 allows remote authenticated users to read published page data. The /api/site/find route returns requested published pages without applying pages.access to the current user, exposing full content and metadata. Exploitation requires a role with pages.access disabled and known or guessed page IDs or UUIDs; draft pages and write actions are unaffected.
