CVE-2026-69204 – HTTP Request Smuggling (CL.TE) – http4s Ember Server before 0.23.35 / 1.0.0-M47

Be the first to know when new zero-days emerge:

Summary

CVE-2026-69204 is a critical HTTP request smuggling vulnerability in the Ember HTTP/1.1 server implementation shipped with the http4s Scala HTTP library. The Ember parser fails to reject requests that contain both Transfer-Encoding and Content-Length headers, violating RFC 9112 §6.1, which allows an attacker to construct CL.TE-style smuggled requests when Ember sits behind a keep-alive intermediary such as a load balancer, reverse proxy, or CDN. The issue carries a CVSS score of 9.2 and can be exploited remotely without authentication.

Technical details

  • Root cause: RFC 9112 §6.1 requires that a server receiving both Transfer-Encoding and Content-Length headers in the same request treat it as a framing error and close the connection. The Ember HTTP/1.1 parser instead accepts both headers and processes the message, rather than rejecting it (CWE-444: Inconsistent Interpretation of HTTP Requests / "HTTP Request Smuggling").
  • Trigger conditions: Ember must be deployed behind an intermediary (proxy, load balancer, CDN, or other front-end) that keeps connections alive/reused and that determines message framing using Content-Length while forwarding the conflicting Transfer-Encoding header downstream to Ember unchanged.
  • Attack vector: Network — a remote, unauthenticated attacker sends a specially crafted HTTP/1.1 request containing both conflicting headers over a connection shared with the intermediary. Because the front-end and Ember disagree on where one request ends and the next begins, part of the attacker’s request is interpreted by Ember as the start of a subsequent, victim request.
  • Impact: Successful exploitation lets an attacker desynchronize the connection to smuggle requests past intermediary access controls, hijack or manipulate other users’ requests/responses on shared connections, and poison caches sitting in front of Ember. On http4s clients that pool connections to an upstream sending dual headers, the same desynchronization can also occur.

Affected software

  • http4s-ember-core (Scala 2.12) — versions ≤ 0.23.34
  • http4s-ember-core (Scala 2.13) — versions ≤ 0.23.34, and 1.0.0-M1 through 1.0.0-M46
  • http4s-ember-core (Scala 3) — versions ≤ 0.23.34, and 1.0.0-M1 through 1.0.0-M46
  • Any application embedding the vulnerable Ember server (or client) via these library versions

Severity

  • CVSS v4.0 Base Score: 9.2 (Critical)
  • Vector: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:L/SC:N/SI:N/SA:N

Mitigation and recommended actions

  • Immediate: Upgrade http4s Ember to a patched release:
    • http4s-ember-core 0.23.x → 0.23.35 or later
    • http4s-ember-core 1.0.0 milestone line → 1.0.0-M47 or later
  • If patching is not immediately possible, apply the following network-level mitigations:
    • Configure any intermediary (proxy, load balancer, CDN) in front of Ember to strictly reject requests that contain both Transfer-Encoding and Content-Length headers.
    • Have the intermediary fully re-encode/normalize request bodies before forwarding rather than passing through the original framing headers unmodified.
    • Disable or avoid keep-alive/connection reuse between the intermediary and Ember-backed services until patched, since request smuggling requires a shared, persistent connection.

How IONIX’s External Exposure Management Platform Detects and Validates
Zero-Days to Shrink MTTR

1

Map your entire attack surface (continously)

IONIX uses multi-factor discovery methods, including DNS analysis, certificate mapping, metadata inspection, and more, to automatically map every internet-facing asset across your environment. This includes cloud instances, third-party platforms, shadow IT, and even forgotten infrastructure that traditional tools miss.

2

Monitor for new CVEs

Dozens of threat intel feeds using agentic technology are continuously analyzed to detect the appearance of proof-of-concept code, exploit kits, and indicators of active targeting. IONIX goes further by applying AI to proactively evaluate whether emerging vulnerabilities are likely to be exploited, even before PoCs go public.

3

Identify Potential External Exposures

Not all CVEs matter. IONIX filters vulnerabilities by asking attacker-centric questions: Can it be reached from the internet? Does it require authentication? Is it being exploited in the wild? This dramatically reduces noise and focuses teams on threats that can actually be weaponized.

4

Create Safe, Scalable Exploit Validations

IONIX transforms real-world PoCs into safe, non-intrusive test payloads that can be run in production environments without disruption. These simulations are precisely targeted to the systems that are vulnerable, ensuring rapid validation without unnecessary load.

5

Execute Exploit Validations

By combining context about software stack, versioning, exposure status, and reachability, IONIX ensures that only the right payloads are executed against the right assets, maximizing efficiency and minimizing risk.

6

Drive Fast and Actionable Remediation

Results are routed through integrations with ticketing, SOAR, and SIEM tools. Issues are written in plain language, bundled into remediation clusters, and prioritized based on asset criticality, exploitability, and blast radius. This shortens mean time to remediation (MTTR) and empowers teams to act with confidence.
