CVE-2019-12399

26
FAUCET Score

CVE-2019-12399 affects Apache Kafka Connect versions 2.0.0 through 2.3.0, where a misconfiguration allows for the exposure of plaintext secrets. When Connect workers use config providers and a connector is created or updated with externalized secret variables within a configuration property, any client can retrieve the connector's task configuration, revealing these secrets. This vulnerability has a CVSS score of 7.5 (High), indicating a network-based attack with low complexity and high confidentiality impact, requiring no privileges or user interaction. There is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant media coverage, though it has seen minimal community discussion.
