# CVE-2026-123537: OpenAM before 16.1.4 SSRF via UMA Scope Description URLs

Status: published. Published: 2026-11-08. Updated: 2026-11-10.

OpenAM before 16.1.4 contains a server-side request forgery vulnerability that allows parties registering UMA resource sets to trigger internal requests through unvalidated scope description URLs. Attackers can register resource sets with scope URLs pointing to internal hosts or cloud metadata endpoints, which OpenAM fetches when sending pending-request notification emails, enabling internal network probing.
