CVE-2025-30159— Kirby 安全漏洞

Kirby vulnerable to path traversal of snippet names in the `snippet()` helper

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 find vulnerable setups through automated methods such as fuzzing. In a vulnerable setup, this could cause damage to the confidentiality and integrity of the server. The problem has been patched in Kirby 3.9.8.3, Kirby 3.10.1.2, and Kirby 4.7.1. In all of the mentioned releases, Kirby maintainers have added a check for the snippet path that ensures that the resulting path is contained within the configured snippets root. Snippet paths that point outside of the snippets root will not be loaded.

对路径名的限制不恰当(路径遍历)

Kirby 安全漏洞

Kirby是Kirby开源的一套基于文件的内容管理系统（CMS）。 Kirby 3.9.8.3之前版本、3.10.1.2之前版本和4.7.1之前版本存在安全漏洞，该漏洞源于缺少路径遍历检查，可能导致文件访问和执行。
