Description

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.
