How to Fix GHSA-hx5q-v6pj-533r

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

com.linecorp.centraldogma:centraldogma-server-auth-saml fixed: 0.64.3 
<dependency>
    <groupId>com.linecorp.centraldogma</groupId>
    <artifactId>centraldogma-server-auth-saml</artifactId>
    <version>0.64.3</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=com.linecorp.centraldogma

How to Check if You Are Affected

To determine whether your Java application is affected by GHSA-hx5q-v6pj-533r, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=com.linecorp.centraldogma

Analyze the terminal output to locate any version of Centraldogma server auth saml in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.64.3), your application is affected.

Note: The mvn dependency:tree -Dincludes=com.linecorp.centraldogma 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-1395: Dependency on Vulnerable Third-Party Component, where the product has a dependency on a third-party component that contains one or more known vulnerabilities. In Centraldogma server auth saml, 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

### Impact When SAML is used as the authentication mechanism, Central Dogma accepts unsigned SAML messages (assertions, logout requests, etc.) as they are, rather than rejecting them by default. As a result, an attacker can forge a SAML message to authenticate themselves, despite the fact that such an unsigned SAML message should be rejected. ### Patches The vulnerability has been patched in Central Dogma 0.64.3 by updating its Armeria dependency to 1.27.2. All users who use SAML as the authentication mechanism must upgrade from 0.64.3 or later. ### Workarounds A user can manually upgrade the `armeria-saml` module with the one from Armeria 1.27.2 or later, either by replacing the JAR in the Central Dogma distribution or by updating the dependency tree of the build. ### References [`SamlMessageUtil.validateSignature()`](https://github.com/line/armeria/blob/0efc776988d71be4da6e506ec8a33c2b7b43f567/saml/src/main/java/com/linecorp/armeria/server/saml/SamlMessageUtil.java#L160-L163)
