Detailsinfo

A vulnerability was found in Element HQ Element Call up to 0.20.2. It has been classified as problematic. This affects an unknown functionality of the component Logging. The manipulation of the argument password with an unknown input leads to a information disclosure vulnerability. CWE is classifying the issue as CWE-200. The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information. This is going to have an impact on confidentiality. The summary by CVE is:

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.
