Technical details
The Planet subscription add action accepts GET requests and lacks proper CSRF token validation, allowing an unauthenticated attacker to induce a global administrator to trigger the action via a crafted web page. The vulnerable code fetches the supplied URL and publishes any parseable feed content without further authentication. The fix requires POST requests with valid CSRF tokens for all Planet admin changes and disables the aggregator by default.
Affected products
