## What is CVE-2026-9270?

CVE-2026-9270 is a critical vulnerability in BINARY DataDog::DogStatsd, published on 5 Jun 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

DataDog::DogStatsd versions through 0.07 for Perl allow metric injections.

DataDog::DogStatsd does not properly sanitise input, allowing metric injections of data from untrusted sources.

The send_stats method does not remove newlines from metric names ($stat variable), allowing attackers to change the metric name prefix.

The send_stats method does not validate the content of the value ($delta variable), allowing attackers to inject metrics, especially from methods that do not restrict the data type for the value, such as set, gauge, count and histogram.

The send_stats method does not validate the content of the tags, which may contain newlines, pipes and colons that allow metric injections.

Note that the SYNOPSIS shows an example of passing a website form "loginName" parameter as a tag, which is unsafe.

Weakness: CWE-93 (Improper Neutralization of CRLF Sequences), CWE-150 (Improper Neutralization of Escape, Meta, or Control Sequences)

Check this codebase for CVE-2026-9270 and fix it if it is affected.

What it is: CVE-2026-9270 is a critical vulnerability in BINARY DataDog::DogStatsd, published on 5 Jun 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2026-9270 in the wild and no public exploit code.

Affected product: BINARY DataDog::DogStatsd. No package-level version data is available, so check the vendor advisory linked from the reference page.

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.
