In a lawsuit filed on September 4th, Elastic, the company behind Elasticsearch and Kibana, accused floragunn GmbH of copying proprietary code for its security plugin, Search Guard, and has since expanded the claim to include additional infringements pertaining to Kibana. The updated lawsuit identifies further copying by floragunn in the Search Guard Kibana plugin, notably in user management features, and highlights third-party products and services that utilize the infringing code, such as Amazon Elasticsearch Service and IBM Cloud Databases for Elasticsearch. Although these companies are not being sued, their use of Search Guard places them in a complex legal situation. Elastic emphasizes that its products offer free security features and encourages Search Guard users to consider these options to avoid running unprotected clusters. Elastic invites users with concerns to reach out for support and clarification.
