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=io.spray

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2018-18855, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=io.spray

Analyze the terminal output to locate any version of Spray json 2.10 in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.3.5), your application is affected.

Note: The mvn dependency:tree -Dincludes=io.spray 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-400: Uncontrolled Resource Consumption, where the product does not properly control the allocation and maintenance of a limited resource. In Spray json 2.10, 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

Recursive decent parsers are susceptible too StackOverflowExceptions on too deeply nested structures as currently "open" parsing state is kept on the stack.
