Kerentanan Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') pada ssw tinacms/cli. Skor CVSS 3.1 8.3 (High) menurut NVD.

Deskripsi (NVD)

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.
