CVE-2026-62379 · Severity: critical · CVSS 9.8 · Published 2026-09-15

OpenAM, an open-source access management solution, is vulnerable to a critical security flaw that allows attackers to take complete control of the server without needing a password. By sending a specially crafted request to the authentication service, an unauthorized user can run malicious code on the system. This could lead to the theft of sensitive user data, service disruption, or a total compromise of the corporate identity infrastructure.

Technologies: [org.openidentityplatform.openam:openam-core (Maven)](https://junglewise.ai/threats/technologies/org-openidentityplatform-openam-openam-core), [Open Identity Platform OpenAM](https://junglewise.ai/threats/technologies/openam). Vendors: [Maven](https://junglewise.ai/threats/vendors/maven), [Open Identity Platform](https://junglewise.ai/threats/vendors/open-identity-platform).

  ```


## Technical details

A remote code execution vulnerability exists in OpenAM's authentication endpoint (/authservice, PLL) due to unsafe use of Class.forName in the AuthXMLUtils.createCustomCallback method. The application accepts an XML element containing a class name and instantiates it without proper validation or sandboxing. Because this endpoint is reachable without authentication in default configurations, a remote attacker can trigger the loading and execution of arbitrary Java classes. This allows for full system compromise. The issue is addressed in version 16.1.2; interim mitigations include enabling sunRemoteAuthSecurityEnabled or restricting network access to the affected endpoint.
