Description
@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.
Recommendation
Update the @tinacms/graphql package to the latest compatible version. Followings are version details:
- Affected version(s): <= 2.2.1
- Patched version(s): 2.2.2
