Home Assistant: XSS in Statistics Graph Card

Published: Sep 22, 2026Updated: Sep 23, 2026 Sources: CVE List NVDCWE-80

N/ACVSS

NVD MITRE

Description

Home Assistant is open source home automation software focused on local control and privacy. Prior to 2026.7.0, the Statistics Graph card in src/components/chart/statistics-chart.ts passed entity names through getStatisticLabel and computeStateName and interpolated param.seriesName into ECharts tooltip HTML without escaping. An authenticated user or an integration that supplies a malicious default entity name could cause script-related HTML to execute when a viewer hovered over a data point. Mean, State, Sum, and Change fields in the default Line chart configuration were affected, while Bar charts were not. This issue is fixed in version 2026.7.0.
