CVE-2025-50199Network attack vector

Unauthenticated SSRF via unvalidated OpenID destination

Published Mar 2, 2026 · Updated Mar 2, 2026

Server-side request forgery in Chamilo LMS before 1.11.30 allows remote attackers to send HTTP requests through the server. The index.php OpenID handler accepts the POST openid_url value without validating its destination before issuing an outbound request. Exploitation requires the OpenID module, which is disabled by default, and exposes restricted internal or external services to server-originated requests.
