Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Home Assistant versions before 2026.7.0 are vulnerable to cross-site scripting in the Statistics Graph card. An authenticated user can give an entity a crafted name, or a name can come from an integration's provider, and the payload runs in the browser of anyone who views that entity on a Line-type Statistics Graph card and hovers over a data point. Upgrade to Home Assistant 2026.7.0 or later. No other workaround is given.
