A flaw was found in Moodle. A site administrator could exploit a blind Server-Side Request Forgery (SSRF) vulnerability. This vulnerability exists in the MNet peers management functionality due to insufficient validation of peer hostnames against the cURL blocked hosts configuration. This could allow an attacker to make the server perform requests to arbitrary domains, potentially leading to information disclosure or other internal network access.
