{"cve":"CVE-2026-91130","nvd":{"published":"2026-09-22T19:16:56.700","modified":"2026-09-23T18:12:04.247","status":"Awaiting Analysis","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.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:A/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H","score":9.3},"cvss_v3":null,"cwes":["CWE-80"],"references":["https://github.com/home-assistant/core/releases/tag/2026.7.0","https://github.com/home-assistant/core/security/advisories/GHSA-wx4m-69m9-gx3m","https://github.com/home-assistant/frontend/commit/b8c201b6d34414d30c622797366570185c219614","https://github.com/home-assistant/frontend/pull/52235","https://github.com/home-assistant/core/security/advisories/GHSA-wx4m-69m9-gx3m"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:56:02.509636177+00:00"},"epss":{"cve":"CVE-2026-91130","score":0.00483,"percentile":0.41668,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-wx4m-69m9-gx3m","url":"https://osv.dev/vulnerability/GHSA-wx4m-69m9-gx3m","summary":"Home Assistant: XSS in Statistics Graph Card","modified":"2026-10-01T17:56:06.655648913Z","packages":[{"ecosystem":"PyPI","name":"homeassistant","purl":"pkg:pypi/homeassistant","ranges":["<2026.7.0"],"fixed":["2026.7.0"]}]},{"id":"PYSEC-2026-4052","url":"https://osv.dev/vulnerability/PYSEC-2026-4052","summary":"Home Assistant: XSS in Statistics Graph Card","modified":"2026-10-01T17:45:03.823298001Z","packages":[{"ecosystem":"PyPI","name":"homeassistant","purl":"pkg:pypi/homeassistant","ranges":["<2026.7.0"],"fixed":["2026.7.0"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
