# OpenAM Authenticated Server-Side Request Forgery (SSRF) via `/sessionservice`

OpenAM's /sessionservice endpoint does not restrict which URLs a logged-in user can register for session event notifications. An authenticated attacker can make the server send outbound requests to arbitrary destinations, potentially exposing session-related data.

_Summary, check and fix written by a model from the sources; labelled as such._

## Affected

- maven:org.openidentityplatform.openam:openam-core affected <= 16.0.6 fixed 16.1.1

## How to check

- Check the `openam-core` version in the project's Maven dependencies; affected versions are `<= 16.0.6`.
- Confirm whether the `/sessionservice` endpoint is reachable from outside the network.

## Fix

- Upgrade `org.openidentityplatform.openam:openam-core` to `16.1.1`.

## From the sources

OpenAM (Open Identity Platform) is an open-source Identity and Access Management (IAM) platform derived from ForgeRock OpenAM, providing SSO, OAuth2, SAML, and OpenID Connect capabilities. It is widely deployed in enterprise environments as a central authentication gateway.

The `/sessionservice` endpoint, used for internal session management operations, does not sufficiently restrict the URLs that authenticated users may register for session event notifications. Under certain conditions, this may result in outbound server-side requests to attacker-controlled destinations, potentially exposing session-related data.

This behavior results in a **server-side request forgery (SSRF)** vulnerability, where an authenticated attacker can trigger outbound requests to arbitrary destinations.
