CVE-2026-54005: CWE-862: Missing Authorization in getkirby kirby
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.
AI Analysis
Technical Summary
CVE-2026-54005 is a missing authorization vulnerability (CWE-862) in the Kirby content management system. In affected versions before 4.9.4 and 5.4.4, if a role has the pages.access permission disabled, authenticated users can still access full content and metadata of arbitrary published pages by providing page IDs or UUIDs to the /api/site/find API endpoint. This bypasses intended access controls, exposing sensitive page data without proper authorization. The vulnerability is resolved in Kirby versions 4.9.4 and 5.4.4.
Potential Impact
Authenticated users with restricted page access permissions can access full content and metadata of arbitrary published pages without authorization. This exposure can lead to information disclosure of potentially sensitive content on affected Kirby sites.
Mitigation Recommendations
Upgrade Kirby CMS to version 4.9.4 or later, or 5.4.4 or later, where this authorization bypass vulnerability is fixed. No other mitigation is indicated by the vendor advisory.
