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-jrpm-956j-96jg)

medium Tenable Cloud Security Plugin ID 447998

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’s chunk decoder trims
 the chunk-size token and accepts leading plus or minus signs instead of requiring one or more hexadecimal
 digits followed by the required CRLF. When an intermediary forwards chunked data without re-encoding and
 interprets malformed chunk boundaries differently, an unauthenticated attacker can create TE.TE request
 smuggling that bypasses intermediary controls, poisons caches, or hijacks the request queue. The same
 response-path leniency can enable response smuggling against an ember-client used as a gateway when the
 upstream is malicious or compromised. This issue is fixed in versions 0.23.35 and 1.0.0-M47.
 (CVE-2026-69216)

Solution

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