AI-suggested

A fix is available in OpenAM version 16.1.4. Users should upgrade to version 16.1.4 or later to remediate this vulnerability. Since this is a server-side vulnerability requiring administrative privileges, applying the official patch is the recommended mitigation.

Description

OpenAM versions prior to 16.1.4 contain a server-side request forgery (SSRF) vulnerability. This flaw allows administrators, including delegated realm administrators, to cause the server to fetch arbitrary URLs via the federation configuration wizard metadata URLs. Malicious metadata or OpenID Connect discovery URLs can be used to probe internal network hosts or cloud metadata endpoints, potentially exposing partial response data.
