Vulnerability details
The vulnerability allows a remote attacker to perform unauthorized state-changing actions.
The vulnerability exists due to missing cross-site request forgery protection in the /share, /feedback, and /esri-token-auth endpoints when processing cross-origin browser requests. A remote attacker can cause the victim's browser to send crafted cross-origin requests to perform unauthorized state-changing actions.
