How to Fix CVE-2026-45052

To remediate this vulnerability, upgrade all affected Openam federation library dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

org.openidentityplatform.openam:openam-federation-library fixed: 16.1.1
<dependency>
    <groupId>org.openidentityplatform.openam</groupId>
    <artifactId>openam-federation-library</artifactId>
    <version>16.1.1</version>
</dependency>
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release:

mvn dependency:tree -Dincludes=org.openidentityplatform.openam

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2026-45052, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=org.openidentityplatform.openam

Analyze the terminal output to locate any version of Openam federation library in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 16.1.1), your application is affected.

Note: The mvn dependency:tree -Dincludes=org.openidentityplatform.openam command inspects the resolved dependency graph declared in your project's POM files; it does not perform automated security scanning or inspect runtime dynamic classpaths. Always verify runtime container classpaths and shaded JARs.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-285: Improper Authorization, where the product does not perform or incorrectly performs an authorization check when an actor attempts to access a resource or perform an action. In Openam federation library, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

## Summary **Description** An Improper Authorization (CWE-285) issue in OpenAM's Liberty Web Services SOAP receiver allows an unauthenticated remote attacker to write persistent entries into the Liberty Discovery store on any user's LDAP entry, and into a shared root-realm Discovery branch. This impacts OpenAM Community Edition through version 16.0.6. This issue was patched in version 16.1.1. Liberty ID-WSF is a legacy protocol superseded by SAML 2.0, OAuth, and OIDC, and deployments that intentionally leverage it assume the risks of an unmaintained federation stack. While Liberty is exposed in the shipped defaults, this bug does not require active Liberty consumers for the write itself. Downstream impact depends on whether anything consumes Discovery data. The endpoint accepts anonymous writes that are performed server-side by the Discovery handlers, bypassing the requester's LDAP and identity ACLs. The global Discovery path explicitly uses the internal admin token. ## Impact OpenAM Community Edition deployments through version 16.0.6 that expose the Liberty Web Services component are potentially affected. An unauthenticated attacker who can reach the relevant endpoint may write persistent records to the discovery store, bypassing normal identity-layer access controls. These writes are performed with elevated internal privileges server-side. In deployments that actively consume Liberty discovery data, manipulated records could influence service routing or security mechanism selection in subsequent requests. The severity of downstream impact varies by deployment.. ## Patch This has been patched in OpenAM Community Edition version 16.1.1. Users are encouraged to update to the latest release.
