CVE-2026-54004 PUBLISHED

Kirby: Access to files of top-level drafts is not protected by permissions

Assigner: GitHub_M
Reserved: 11.06.2026 Published: 09.07.2026 Updated: 09.07.2026

Kirby is an open-source content management system. Prior to 4.9.4 and 5.4.4, Kirby sites with content.fileRedirects enabled could redirect unauthenticated clean file URL requests for files stored in top-level draft pages to physical media URLs without checking page access permissions or preview tokens, leading to disclosure of draft file contents. This issue is fixed in versions 4.9.4 and 5.4.4.
