## What is CVE-2024-32890?

CVE-2024-32890 is a medium-severity cross-site scripting vulnerability in librespeed speedtest, published on 1 May 2024. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.

### Official description

librespeed/speedtest is an open source, self-hosted speed test for HTML5. In affected versions missing neutralization of the ISP information in a speedtest result leads to stored Cross-site scripting in the JSON API. The `processedString` field in the `ispinfo` parameter is missing neutralization. It is stored when a user submits a speedtest result to the telemetry API (`results/telemetry.php`) and returned in the JSON API (`results/json.php`). This vulnerability has been introduced in commit 3937b94. This vulnerability affects LibreSpeed speedtest instances running version 5.2.5 or higher which have telemetry enabled and has been addressed in version 5.3.1. Users are advised to upgrade. There are no known workarounds for this vulnerability.

Weakness: CWE-79 (Improper Neutralization of Input During Web Page Generation)

What it is: CVE-2024-32890 is a medium-severity cross-site scripting vulnerability in librespeed speedtest, published on 1 May 2024. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.
Exploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2024-32890 exists.

Affected product: librespeed speedtest. 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.
