Description
The HTTP/1.1 parser incorrectly handles quoted strings within chunked transfer encoding extension values. Specifically, the parser terminates chunk header parsing when it encounters a carriage return and line feed (CRLF) sequence inside a quoted string instead of treating it as a parsing error. This behavior allows an attacker to inject smuggled HTTP requests, which can lead to cache poisoning, access control bypass, and session hijacking.
