How to Fix CVE-2025-62784

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

de.themoep:inventorygui fixed: 1.6.5 
<dependency>
    <groupId>de.themoep</groupId>
    <artifactId>inventorygui</artifactId>
    <version>1.6.5</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=de.themoep

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2025-62784, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=de.themoep

Analyze the terminal output to locate any version of Inventorygui in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.6.5), your application is affected.

Note: The mvn dependency:tree -Dincludes=de.themoep 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-837: Improper Enforcement of a Single, Unique Action, where the product requires that an actor should only be able to perform an action once, or to have only one unique action, but the product does not enforce or improperly enforces this restriction. In Inventorygui, 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 Any plugin using a GUI with the GuiStorageElement and allows taking out items out of that element. ### Patches InventoryGui 1.6.5 (included in latest 1.6.5-SNAPSHOT) by disabling GuiStorageElement when not running on 1.21.9 or later. ### Workarounds Not using the GuiStorageElement.
