## Affected

- element-hq element-desktop: from 1.11.70, fixed in 1.11.81

## Description

Element Desktop is a Matrix client for desktop platforms. Element Desktop versions 1.11.70 through 1.11.80 contain a vulnerability which can, under specially crafted conditions, lead to the access token becoming exposed to third parties. At least one vector has been identified internally, involving malicious widgets, but other vectors may exist. Users are strongly advised to upgrade to version 1.11.81 to remediate the issue. As a workaround, avoid granting permissions to untrusted widgets.

## What to do
