| "summary": "Improper access to parent directory of root in os", |
| "details": "It was possible to improperly access the parent directory of an os.Root by opening a filename ending in \"../\". For example, Root.Open(\"../\") would open the parent directory of the Root. This escape only permits opening the parent directory itself, not ancestors of the parent or files contained within the parent.", |
