• CVE-2026-44202: 0.41% estimated exploitation activity in the next 30 days; percentile 35.70 (FIRST EPSS, 2026-11-03). This is a model estimate, not proof of exploitation or customer exposure.

As published by the source; long descriptions are shortened.

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.

# Patch Next advisory brief: CVE-2026-44202

Advisory: OpenAM Authenticated Server-Side Request Forgery (SSRF) via `/sessionservice`
IDs: CVE-2026-44202, GHSA-c556-q2mh-477v
Record: https://patchnext.com/advisories/cve-2026-44202 (revision 3, source checked 29 Oct 2026, 06:45 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Medium (CVSS 6.2)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: org.openidentityplatform.openam:openam-core 16.1.1. A vendor fix does not mean a deployment is fixed.

## Affected components
- Maven org.openidentityplatform.openam:openam-core: affected < 16.1.1; fixed in 16.1.1

## Suggested inspection (read-only)
- Maven org.openidentityplatform.openam:openam-core: check the installed version with your package manager.

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on org.openidentityplatform.openam:openam-core.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.
