How to Fix CVE-2023-30532

To remediate this vulnerability, upgrade all affected Spoonscript 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.jenkinsci.plugins.spoonscript:spoonscript fixed: Latest secure release 
<dependency>
    <groupId>org.jenkinsci.plugins.spoonscript</groupId>
    <artifactId>spoonscript</artifactId>
    <version>Latest secure release</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.jenkinsci.plugins.spoonscript

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2023-30532, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=org.jenkinsci.plugins.spoonscript

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

Note: The mvn dependency:tree -Dincludes=org.jenkinsci.plugins.spoonscript 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-862: Missing Authorization, where the product does not perform an authorization check when an actor attempts to access a resource or perform an action. In Spoonscript, 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

A missing permission check in Jenkins TurboScript Plugin 1.3 and earlier allows attackers with Item/Read permission to trigger builds of jobs corresponding to the attacker-specified repository.
