Summary
matrix-react-sdk is a Matrix chat protocol SDK for React Javascript.

The remainder of the application can appear functional, though certain rooms/events will not be rendered. This issue has been fixed in matrix-react-sdk 3.53.0 and users are advised to upgrade. There are no known workarounds for this vulnerability.
