Summary

OpenIdentityPlatform OpenAM before 16.1.4 contains a server-side request forgery flaw (CWE-918) in how it handles UMA resource sets. OpenAM does not validate scope description URLs, so it fetches them when sending pending-request notification emails. A remote attacker with low privileges who can register UMA resource sets can make OpenAM send requests to internal hosts and cloud metadata endpoints, which allows internal network probing.

Description from the CNA

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.
