Vulnerability details
The vulnerability allows a remote attacker to disclose sensitive information.
The vulnerability exists due to permissive cross-domain security policy with untrusted domains in the CORS handling of @strapi/core when handling cross-origin requests. A remote attacker can host an attacker-controlled origin and send credentialed requests to disclose sensitive information.
Default installations reflect the Origin header in the Access-Control-Allow-Origin response header and allow credentials in cross-origin responses.
