  The vulnerability can be exploited with a single GET request which can be triggered via
  cross-site request forgery. For this, an attacker can craft a malicious email and include an
  external image that when rendered exploits the vulnerability without further interaction of a
  victim. The only requirement is to have a victim open the malicious email.");
