Description

Element Call is a native Matrix video conferencing application. From 0.16.0 until 0.20.3, the standalone Element Call `SPA` logs the `password` URL query parameter. When a user submits an error report, called a rageshake, these logs are shared with the application operator. Users can therefore unintentionally disclose the shared `password` used to encrypt the call, potentially compromising call confidentiality. Avoiding submission of bug reports or debug logs prevents this disclosure path in affected versions. Upgrading does not remove secrets from previously collected `rageshakes`, which require separate cleanup by the log-server operator. This issue is fixed in version 0.20.3.

Affected products
