Vulnerability details
The vulnerability allows a remote attacker to disclose sensitive information.
The vulnerability exists due to a permissive cross-domain security policy with untrusted domains in the XML-RPC server CORS handling when processing cross-origin requests to /RPC2. A remote attacker can serve a malicious web page that sends a crafted CORS simple request to disclose sensitive information.
User interaction is required, and the issue is triggered when the XML-RPC server is configured with two or more cors_origins entries.
