@tinacms/graphql's Media Endpoints Can Escape the Media Root via Symlinks or Junctions

Tina is a headless content management system. Prior to version 2.2.2, @tinacms/cli recently added lexical path-traversal checks to the dev media routes, but the implementation still validates only the path string and does not resolve symlink or junction targets. If a link already exists under the media root, Tina accepts a path like pivot/written-from-media.txt as "inside" the media directory and then performs real filesystem operations through that link target. This allows out-of-root media listing and write access, and the same root cause also affects delete. This issue has been patched in version 2.2.2.

对路径名的限制不恰当(路径遍历)

TinaCMS 安全漏洞

TinaCMS是Tina开源的一个用于 Markdown、MDX 和 JSON 的开源无头 CMS。 TinaCMS 2.2.2之前版本存在安全漏洞，该漏洞源于开发媒体路由中的路径遍历检查未解析符号链接目标，可能导致根目录外媒体列表和写入访问。
