CVE-2026-105122

OpenAM before 16.1.3 contains a server-side request forgery vulnerability that allows attackers able to register or modify OAuth 2.0 clients to make OpenAM fetch internal resources via an unvalidated jwks_uri. Attackers can trigger unauthenticated fetches through client-authentication and ID-token validation to probe internal hosts, metadata endpoints or local files, or exhaust request threads for denial of service.
