Summary

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.

Fencer Vulns keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.

CPEs and fixed versions use Anchore's correction of NVD's data: Added CPE configurations because not yet analyzed by NVD.
