CVE-2025-30159

Kirby is an open-source content management system. A vulnerability in versions prior to 3.9.8.3, 3.10.1.2, and 4.7.1 affects all Kirby sites that use the snippet() helper or $kirby->snippet() method with a dynamic snippet name (such as a snippet name that depends on request or user data). Sites that only use fixed calls to the snippet() helper/$kirby->snippet() method (i.e. calls with a simple string for the snippet name) are not affected. A missing path traversal check allowed attackers to navigate and access all files on the server that were accessible to the PHP process, including files outside of the snippets root or even outside of the Kirby installation. PHP code within such files was executed. Such attacks first require an attack vector in the site code that is caused by dynamic snippet names, such as snippet('tags-' . get('tags')). It generally also requires knowledge of the site structure and the server's file system by the attacker, although it can be possible to
