This weakness corresponds to a classic data\u2011exposure flaw (CWE\u2011200).", "risk_and_exploitability": "The CVSS score of 4.6 indicates a moderate security risk, but the EPSS score of less than 1% and absence from the KEV catalog suggest low exploitation probability. The flaw is exploitable only when an attacker can physically reach the UART port, meaning the threat surface is limited to environments where physical access is possible. No remote exploitation path is described, and no additional authentication bypass is required beyond the physical connection to the debug interface."}}}}, "created": "2026-04-07T07:16:12.015107+00:00", "title": "Information Disclosure via UART Debug Interface in AZIOT 1 Node Smart Switch", "updated": "2026-04-09T08:29:07.916244+00:00", "vendors": ["aziot", "aziot$PRODUCT$node_smart_switch"]}
