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.
CVE-2024-32890
This medium-severity CVE scores 6.1 under NVD CVSS v3. EPSS exploit probability: 0.5%, top 59% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).
- Lower severity and no public exploit yet
No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.
