HTTP Request Smuggling

Overview Affected versions of this package are vulnerable to HTTP Request Smuggling in the HTTP/1.1 parsing process. An attacker can bypass front-end controls, capture another user's headers, or poison a cache by sending requests with differing duplicate Content-Length headers, especially when th...

CVE-2026-69217

Http4s is a Scala interface for HTTP services. Prior to 0.23.35 and 1.0.0-M47, Ember’s HTTP/1.1 parser accepts differing duplicate Content-Length headers and uses the last value instead of rejecting the message. When an Ember server is behind a keep-alive intermediary that selects a different...

CVE-2026-69205

Http4s is a Scala interface for HTTP services. Prior to 0.23.35 and 1.0.0-M47, Ember’s HeaderP.parse uses a case-sensitive substring test for the Transfer-Encoding value and decodes header bytes with the platform default charset. Values such as Chunked are not recognized, values such as notchunke...

CVE-2026-18424

Concrete CMS 9.0.0 to 9.5.2 is vulnerable to Server-Side Request Forgery iremote file import via cross-port reuse of a host's validated DNS pin. When multiple remote URLs share the same host, only the first ValidatedRemoteUrl is retained and reused for every later URL with that host. A...

CVE-2026-89040

Tencent Mass Service Engine in Cluster (MSEC) is affected by a path traversal vulnerability that allows a remote, unauthenticated attacker to send a crafted POST request containing ../, gaining root access on the target device. An attacker who uploads a webshell can then execute arbitrary code as...

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...

GHSA-9998-894R-FWVR 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...
