Upgrade matrix-js-sdk to version 34.8.0 or higher.
Overview
matrix-js-sdk is a Matrix Client-Server SDK for Javascript
Affected versions of this package are vulnerable to Improper Authentication through the sendSharedHistoryKeys method. An attacker can intercept and obtain sensitive historical keys by injecting malicious devices into the communication without proper verification of the user's cryptographic identity. This is only exploitable if the client is running the legacy crypto stack.
Note:
This vulnerability does not affect users using the new Rust cryptography stack (i.e., those that call MatrixClient.initRustCrypto() instead of MatrixClient.initCrypto()).
