  "details": "## Summary\n\nAlice runs `zrok2 copy` from a WebDAV or zrok drive controlled by Bob into a local filesystem target. Bob returns a DAV `href` such as `/../outside.txt`. The sync pipeline stores that path in the source inventory and passes it to `FilesystemTarget.WriteStream`, which joins it with the target root and creates the file outside Alice\u0027s selected directory.\n\n### Impact\nUsers given access to a zrok share may be able to traverse the directory tree arbitrarily with the sharing users credentials, allowing for sensitive information to be overwritten.",
