SCA: security update for org.openidentityplatform.openam:openam (GHSA-2cqq-rpvq-g5qj)

critical Tenable Self-Hosted Container Security Plugin ID 439965

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Open Access Management (OpenAM) is an access management solution. Prior to 16.0.6, OpenIdentityPlatform
 OpenAM is vulnerable to pre-authentication Remote Code Execution (RCE) via unsafe Java deserialization of
 the jato.clientSession HTTP parameter. This bypasses the WhitelistObjectInputStream mitigation that was
 applied to the jato.pageSession parameter after CVE-2021-35464. An unauthenticated attacker can achieve
 arbitrary command execution on the server by sending a crafted serialized Java object as the
 jato.clientSession GET/POST parameter to any JATO ViewBean endpoint whose JSP contains <jato:form> tags
 (e.g., the Password Reset pages). This vulnerability is fixed in 16.0.6. (CVE-2026-33439)

Solution

Update the org.openidentityplatform.openam:openam library and its related packages to version 16.0.6 or later.
