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

openHAB, a provider of open-source home automation software, has add-ons including the visualization add-on CometVisu. Several endpoints in versions prior to 4.2.1 of the CometVisu add-on of openHAB don't require authentication. This makes it possible for unauthenticated attackers to modify or to steal sensitive data. This issue may lead to sensitive information disclosure. Users should upgrade to version 4.2.1 of the CometVisu add-on of openHAB to receive a patch.

Detection & mitigation playbook

Open-source dependency

  1. Detect

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

  2. Fix

    Update org.openhab.ui.bundles:org.openhab.ui.cometvisu to 4.2.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-3g4c-hjhr-73rj is resolved across your whole dependency graph.

  3. Workarounds

    Put an independent control in front of the weakness: restrict the affected endpoint or interface to trusted networks, require an additional authentication factor or proxy-level check, and invalidate existing sessions and credentials in case the flaw has already been used.

Frequently Asked Questions
