Grav Grav是Grav组织开源的一个基于文件系统的无数据库内容管理系统。 Grav 1.0.10之前版本存在输入验证错误漏洞，该漏洞源于POST /pages/{route}/move端点中的slug字段验证不当，PagesController::move()仅使用ltrim($body['slug'], '.')清理slug，未能中和'/'或'..'段，可能导致具有api.pages.write权限的已认证API调用者通过路径遍历攻击将整个页面目录移动到任意可写位置。

Vulnerability Title
Grav API Plugin before 1.0.10 Path Traversal via move
Source: CVE Program / CVE List V5
Vulnerability Description
Grav API Plugin (Composer package getgrav/grav-plugin-api) before 1.0.10 fails to properly validate the slug field in the POST /pages/{route}/move endpoint. PagesController::move() sanitizes the slug only with ltrim($body['slug'], '.'), which strips leading periods but does not neutralize '/' or '..' segments. An authenticated API caller with the api.pages.write permission can supply path traversal sequences (e.g., 01.home/../../../pwned) to move an entire page directory (content and media) to an arbitrary writable location outside user/pages/, including outside the Grav installation.
