Description The HTTP/2 server's request validator passed only :method, :path, and :authority through a normalizer that rejects CR/LF/CTL but permits SP/HTAB and applies no host or token grammar. As a result a :method such as "GET /admin?x=" was accepted, :path could carry interior whitespace, and...
