This issue was addressed with improved handling of symlinks. This issue is fixed in macOS Sonoma 14.4. An app may be able to create symlinks to protected regions of the disk.
The product attempts to access a file based on the filename, but it does not properly prevent that filename from identifying a link or shortcut that resolves to an unintended resource.
The product, when opening a file or directory, does not sufficiently account for when the file is a symbolic link that resolves to a target outside of the intended control sphere. This could allow an attacker to cause the product to operate on unauthorized files.
