Exposure of Sensitive Information to an Unauthorized Actor
CVE-2024-47824
Summary
matrix-react-sdk is a react-based software development kit for inserting a Matrix chat/VOIP client into a web page. Starting in version 3.18.0-rc.1 through 3.101.0, matrix-react-sdk allows a malicious homeserver to potentially steal message keys for a room when a user invites another user to that room via injection of a malicious device controlled by the homeserver. This issue is fixed by disabling sharing message keys on invites by removing calls to the vulnerable functionality. No known workarounds are available.
