OpenAM vulnerability

Open Access Management (OpenAM) is an access management solution. Prior to 16.1.1, the /sessionservice addSessionListener operation allows an authenticated user to register an arbitrary notification URL without requiring an administrative or application client token. SessionRequestHandler passes the attacker-controlled destination to the session listener service, causing the OpenAM server to make outbound requests and potentially disclose session-related notification data to an attacker-controlled destination. This issue is fixed in version 16.1.1.
