## What is CVE-2026-2332?

CVE-2026-2332 is a high-severity vulnerability in Eclipse Jetty, published on 14 Apr 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

In Eclipse Jetty, the HTTP/1.1 parser is vulnerable to request smuggling when chunk extensions are used, similar to the "funky chunks" techniques outlined here:
  *  https://w4ke.info/2025/06/18/funky-chunks.html

  *  https://w4ke.info/2025/10/29/funky-chunks-2.html

Jetty terminates chunk extension parsing at \r\n inside quoted strings instead of treating this as an error.

POST / HTTP/1.1
Host: localhost
Transfer-Encoding: chunked

1;ext="val
X
0

GET /smuggled HTTP/1.1
...

Note how the chunk extension does not close the double quotes, and it is able to inject a smuggled request.

Weakness: CWE-444 (Inconsistent Interpretation of HTTP Requests)

Task:
1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.
2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.
3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.
4. Run the tests and summarise what changed and why.
5. If nothing in the project is affected, say so and change nothing.
