This section of the
update_metadatacommand is part of a flow that is vulnerable to a critical Path Traversal vulnerability. Thebase_url(which can be configured by the user) is passed tometadata::update_metadata, which fetches amanifest.json. Thepathfield from this manifest is used to construct local file paths usingmetadata_dir.join(path)without proper sanitization. This allows an attacker to provide paths containing..or absolute paths, leading to arbitrary file writes and potential Remote Code Execution (RCE).Additionally, the current implementation hardcodes the metadata version to
None(which resolves tolatest), overriding any user-configured version set in the frontend. This means if a user sets a specific metadata version in the frontend, it will be ignored.To remediate the Path Traversal, strict path validation must be implemented in
src-tauri/src/services/metadata.rsto ensure the resulting path remains within the intended directory. For the versioning issue, theupdate_metadatacommand should be modified to accept aversionparameter from the frontend and pass it to theservices::metadata::update_metadatafunction. This will also require corresponding frontend changes insrc/api/tauriCommands.tsandsrc/stores/app.ts.
