CVE-2026-62347 · Severity: info · Published 2026-10-30

Element Call is a Matrix-based video conferencing application. In versions 0.16.0 through 0.20.2, the app logs the password used to encrypt calls as part of its debug output. When users submit error reports (rageshakes), these logs containing the call password are sent to the application operator, potentially exposing the encryption credential to unauthorized parties.

## How to fix

- Fixed in 0.20.3

Avoid submitting error reports or debug logs in affected versions. Note that upgrading does not retroactively remove secrets from previously collected rageshakes, which require separate cleanup by the log-server operator.

## Technical details

The standalone Element Call SPA unintentionally logs the password URL query parameter during normal operation. When users submit rageshakes (debug reports), the logs are bundled and transmitted to the operator, inadvertently disclosing the call encryption password. This is a logging/information disclosure issue affecting versions 0.16.0 through 0.20.2, fixed by redacting the password parameter from logs.

## Affected products
