CVE-2026-54005

HIGH

Kirby: `pages.access` permission is not checked in the `site/find` REST API route

Title source: cna
STIX 2.1

Description

Kirby is an open-source content management system. Prior to 4.9.4 and 5.4.4, Kirby sites where a role has the pages.access permission disabled allowed authenticated users who know or guess page IDs or UUIDs to retrieve page information, including full content and metadata, for arbitrary published pages through the /api/site/find route without authorization to access those pages. This issue is fixed in versions 4.9.4 and 5.4.4.
