TinaCMS GraphQL allows malicious file creation and deletion

Summary

An authenticated user can create, move, or delete files outside the intended directory using TinaCMS's GraphQL API. This can lead to unintended data exposure or tampering. To fix this, ensure you're using the latest version of TinaCMS and consider restricting permissions to prevent users from accessing sensitive areas.

Original description

Tina is a headless content management system. Prior to 2.1.2, TinaCMS allows users to create, update, and delete content documents using relative file paths (relativePath, newRelativePath) via GraphQL mutations. Under certain conditions, these paths are combined with the collection path using path.join() without validating that the resolved path remains within the collection root directory. Because path.join() does not prevent directory traversal, paths containing ../ sequences can escape the intended directory boundary. This vulnerability is fixed in 2.1.2.
