Prior to version 2.0.11, `clean_uri()` in libks\u0027s HTTP request parser fails to reject URIs whose path has more segments than its internal canonicalization buffer can hold. The canonicalization step silently passes such URIs through with embedded \"..\" sequences intact, enabling path traversal in any consumer that later joins the URI with a filesystem path. Version 2.0.11 patches the issue."
