How to Fix CVE-2026-8759

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

com.ibeetl:beetl-spring-classic fixed: Latest secure release 
<dependency>
    <groupId>com.ibeetl</groupId>
    <artifactId>beetl-spring-classic</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=com.ibeetl

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2026-8759, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=com.ibeetl

Analyze the terminal output to locate any version of Spring Framework 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=com.ibeetl 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-20: Improper Input Validation, where the product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. In Spring Framework, 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 vulnerability was identified in xiandafu beetl up to 3.20.2. Affected is an unknown function of the file beetl-classic-integration/beetl-spring-classic/src/main/java/org/beetl/ext/spring/SpELFunction.java of the component SpELFunction. The manipulation leads to improper neutralization of special elements used in an expression language statement. Remote exploitation of the attack is possible. The exploit is publicly available and might be used. The project was informed of the problem early through an issue report but has not responded yet.
