Advisory Summary

CVE-2026-93710 is a HIGH (CVSS 7.5) security vulnerability vulnerability (CWE-460: Improper Cleanup on Thrown Exception) affecting Software libraries in the Maven ecosystem. The weakness occurs when the product does not clean up its state or incorrectly cleans up its state when an exception is thrown, leading to unexpected state or control flow.. Remediation is available in the latest vendor maintenance releases.

How to Fix CVE-2026-93710

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

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

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2026-93710, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree

Analyze the terminal output to locate any version of Software 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 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-460: Improper Cleanup on Thrown Exception, where the product does not clean up its state or incorrectly cleans up its state when an exception is thrown, leading to unexpected state or control flow. In Software, 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

Dancer2 versions from 2.0.0 before 2.2.0 for Perl dispatch a route that a dying hook refused when the exception handler halts the response in compile_hooks. A hook that dies fires core.app.hook_exception, then calls cleanup unless the failing hook is the exception handler. A handler that halts does not stop that cleanup, which discards the request, response and session the dispatcher has yet to read, so the refused route runs. The handler has to halt the response object by calling its halt method or setting is_halted: the halt keyword unwinds through with_return before cleanup runs. A check in a before hook is not enforced: the caller gets the refusal, while the route body runs and its writes land.
