SCA: security update for org.http4s:http4s-ember-core_2.12, org.http4s:http4s-ember-core_2.13, org.http4s:http4s-ember-core_3 (GHSA-8h4c-x2wg-6xp8)

critical Tenable Self-Hosted Container Security Plugin ID 448008

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - 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 that forwards
 both headers and frames by Content-Length, an unauthenticated attacker can smuggle a second request,
 bypass intermediary access controls, poison caches, or cause a victim request to be joined to an attacker-
 controlled prefix. The shared response parser can also desynchronize an ember-client connection when a
 malicious or compromised upstream sends both headers. This issue is fixed in versions 0.23.35 and
 1.0.0-M47. (CVE-2026-69204)

Solution

Update the org.http4s:http4s-ember-core_2.12 library and its related packages to version 0.23.35 or later.
