## Technical details

The vulnerability is an unauthenticated server-side request forgery (SSRF) in a legacy endpoint of Commvault Command Center related to improper handling of arbitrary target URLs. The affected endpoint requires no authentication, allowing any network-accessible attacker to craft requests that cause the server to perform HTTP/HTTPS requests to arbitrary internal or external targets. An attacker can exploit this to access internal services, retrieve metadata from cloud environments, or probe the organization's internal network topology. The vulnerability affects Commvault versions 11.46.0–11.46.9, 11.44.0–11.44.10, 11.40.0–11.40.62, and 11.36.0–11.36.113 on Linux and Windows platforms.
