How to Fix CVE-2026-6125
To remediate this vulnerability, upgrade all affected Warm flow plugin modes sb dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.
<dependency>
<groupId>org.dromara.warm</groupId>
<artifactId>warm-flow-plugin-modes-sb</artifactId>
<version>1.8.5</version>
</dependency>Run the following command in your project directory to verify that all resolved dependencies use the patched release:
mvn dependency:tree -Dincludes=org.dromara.warmHow to Check if You Are Affected
To determine whether your Java application is affected by CVE-2026-6125, inspect your build dependencies using the Maven Dependency Plugin:
mvn dependency:tree -Dincludes=org.dromara.warmAnalyze the terminal output to locate any version of Warm flow plugin modes sb in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.8.5), your application is affected.
Note: The mvn dependency:tree -Dincludes=org.dromara.warm 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-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection'), where the product constructs all or part of a command, data structure, or record using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify how it is parsed or interpreted when it is sent to a downstream component. In Warm flow plugin modes sb, software state validation or input boundaries are circumvented during processing.
