Summary

Matrix SDK for React's URL preview setting for a room is controllable by the homeserver

Details

Impact

A malicious homeserver could manipulate a user's account data to cause the client to enable URL previews in end-to-end encrypted rooms, in which case any URLs in encrypted messages would be sent to the server.

Even if the CVSS score would be 4.1 (AV:N/AC:L/PR:H/UI:N/S:C/C:L/I:N/A:N) the maintainer classifies this as High severity issue.

Patches

This was patched in matrix-react-sdk 3.105.1.

Workarounds

Deployments that trust their homeservers, as well as closed federations of trusted servers, are not affected.
