How to Fix CVE-2025-56769

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

cn.hutool:hutool-extra fixed: 5.8.40 
<dependency>
    <groupId>cn.hutool</groupId>
    <artifactId>hutool-extra</artifactId>
    <version>5.8.40</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=cn.hutool

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2025-56769, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=cn.hutool

Analyze the terminal output to locate any version of Hutool extra in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 5.8.40), your application is affected.

Note: The mvn dependency:tree -Dincludes=cn.hutool 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-917: Improper Neutralization of Special Elements used in an Expression Language Statement ('Expression Language Injection'), where the product constructs all or part of an expression language (el) statement in a framework such as a java server page (jsp) using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended el statement before it is executed. In Hutool extra, 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

An issue was discovered in chinabugotech hutool before 5.8.40 allowing attackers to execute arbitrary expressions that lead to arbitrary method invocation and potentially remote code execution (RCE) via the QLExpressEngine class.
