Real-World Exposure

1 pkg affected
☕net.opentsdb:opentsdb

Real-time download stats are indexed for npm and PyPI packages. This vulnerability affects Maven packages — download data is not available via public APIs for these ecosystems.

Description

Due to insufficient validation of parameters reflected in error messages by the legacy HTTP query API and the logging endpoint, it is possible to inject and execute malicious JavaScript within the browser of a targeted OpenTSDB user. This issue shares the same root cause as CVE-2018-13003, a reflected XSS vulnerability with the suggestion endpoint.

Detection & mitigation playbook

Open-source dependency

  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for net.opentsdb:opentsdb, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Remediation status

    The records we use list no patched version of net.opentsdb:opentsdb for GHSA-9chv-3w6c-jq9w. Check the maintainer's advisory, and where your build allows, override or pin the dependency away from the vulnerable range.

  3. Mitigate without a patch

    Escape or sanitise the affected output on the server side rather than relying on client-side filtering, and add a Content-Security-Policy that blocks inline script execution so injected markup cannot run even if it reaches the page.
