| summary: Improper sanitization of Transfer-Encoding headers in net/http |
| 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. |
