| Doc Text: |
A vulnerability was found in python-hyper/h2 that contains an input validation flaw that allows carriage return and line feed (CRLF) characters to be injected into HTTP/2 header fields. When requests are downgraded from HTTP/2 to HTTP/1.1, the library fails to enforce proper header validation, which may lead to incorrect parsing of request boundaries by downstream components.
