Vulnerability details

The vulnerability allows a remote attacker to hijack a user's session and take over the account.

The vulnerability exists due to exposure of sensitive information to an unauthorized actor in /objects/phpsessionid.json.php when handling credentialed cross-origin requests. A remote attacker can host a crafted webpage that triggers a cross-origin request and reads the returned session ID to hijack a user's session and take over the account.
