Overview
Affected versions of this package are vulnerable to Arbitrary Code Injection in the process that renders the Gallery or Kanban view when a malicious URL is stored in the mAsset field and used as a cover image. An attacker can execute arbitrary operating system commands under the victim's user account by injecting JavaScript code that is executed when the victim opens the affected view in the Electron desktop client.
Note:
This is only exploitable if the desktop client is configured with nodeIntegration enabled and contextIsolation disabled.
