What is CVE-2025-30207?

A path traversal vulnerability exists in Kirby CMS versions before 3.9.8.3, 3.10.1.2, and 4.7.1, affecting setups using PHP's built-in server, typically used during local development. Attackers can exploit this flaw to navigate files accessible to the PHP process, including those outside the installation directory. Although the contents of these files are not exposed by PHP, the vulnerability allows for detection of the existence of these files. The issue has been mitigated in the latest versions, where the router now checks the document root to prevent unauthorized access beyond it, returning an error page for requests outside the valid scope.
