| description: | |
| The HTTP/1 client accepted some invalid Transfer-Encoding headers as |
| indicating a "chunked" encoding. This could potentially allow for request |
| smuggling, but only if combined with an intermediate server that also |
| improperly failed to reject the header as invalid. |

| Acceptance of some invalid Transfer-Encoding headers in the HTTP/1 client |

| reject the header as invalid. |
