Matrix developers report:

Today we are issuing security releases of matrix-js-sdk and matrix-react-sdk to patch a pair of High severity vulnerabilities (CVE-2023-28427 / GHSA-mwq8-fjpf-c2gr for matrix-js-sdk and CVE-2023-28103 / GHSA-6g43-88cp-w5gv for matrix-react-sdk).

The issues involve prototype pollution via events containing special strings in key locations, which can temporarily disrupt normal functioning of matrix-js-sdk and matrix-react-sdk, potentially impacting the consumer's ability to process data safely.
