Http4s Ember Transfer-Encoding value parsing (TE.CL / TE.0 request smuggling)

Summary Ember's HTTP/1.1 header parser matches the Transfer-Encoding header value with a case-sensitive substring test hValue.contains"chunked". RFC 9112 §7 requires transfer-coding names to be compared case-insensitively. A request carrying Transfer-Encoding: Chunked capital C is therefore not...

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...

CVE-2026-69204

Http4s is a Scala interface for HTTP services. Prior to 0.23.35 and 1.0.0-M47, Ember HTTP/1.1 does not reject messages containing both Transfer-Encoding and Content-Length, so an intermediary and Ember can select different body framing rules. When ember-server is behind a keep-alive intermediary...

CVE-2026-69205

Http4s (a Scala HTTP library) is affected in its Ember backend, specifically the HeaderP.parse function, which uses a case-sensitive substring test for the Transfer-Encoding value and decodes header bytes with the platform default charset. This causes mismatches with RFC-compliant intermediaries,...
