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.mapfish.print

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2026-44672, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=org.mapfish.print

Analyze the terminal output to locate any version of Mapfish Print in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 3.28.28), your application is affected.

Note: The mvn dependency:tree -Dincludes=org.mapfish.print 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-94: Improper Control of Generation of Code ('Code Injection'), where the product constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment. In Mapfish Print, 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.
