HTTP Request Smuggling

Http4s is vulnerable to HTTP Request Smuggling. The vulnerability is due to inconsistent HTTP message body framing between Ember and an intermediary when both headers are present, which allows an attacker to smuggle a second request, bypass access controls, poison caches, or cause a victim reques...

Http4s: Ember HTTP/2 buffers a frame's declared payload before checking SETTINGS_MAX_FRAME_SIZE

Summary An unauthenticated peer can make Ember's HTTP/2 read loop hold 16 MiB of a single frame in memory on a connection where Ember advertised a 16 KiB limit. The declared length is readable from the frame's first 9 bytes, but it is not compared against SETTINGSMAXFRAMESIZE until the whole...

Http4s: Ember chunk parser lenience (TE.TE request smuggling)

Summary Ember's chunk decoder parses the size token leniently: it strips leading and trailing whitespace and accepts a leading + or - sign. RFC9112 §7.1 defines chunk-size = 1HEXDIG. An intermediary that parses the chunk boundary differently or rejects it will disagree with Ember on request...

Http4s Ember accepts Transfer-Encoding combined with Content-Length (CL.TE request smuggling)

Summary Ember's HTTP/1.1 request parser does not reject a message that carries both a Transfer-Encoding and a Content-Length header. RFC 9112 §6.1 requires a server to treat such a message as a framing error and close the connection. An intermediary that follows the RFC's CL-strip-and-forward pat...
