How to Fix CVE-2022-43407

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

org.jenkins-ci.plugins:pipeline-input-step fixed: 456.vd8a_957db_5b_e9
<dependency>
    <groupId>org.jenkins-ci.plugins</groupId>
    <artifactId>pipeline-input-step</artifactId>
    <version>456.vd8a_957db_5b_e9</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=org.jenkins-ci.plugins

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2022-43407, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=org.jenkins-ci.plugins

Analyze the terminal output to locate any version of Pipeline input step in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 456.vd8a_957db_5b_e9), your application is affected.

Note: The mvn dependency:tree -Dincludes=org.jenkins-ci.plugins 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-352: Cross-Site Request Forgery (CSRF), where the web application does not, or cannot, sufficiently verify whether a request was intentionally provided by the user who sent the request, which could have originated from an unauthorized actor. In Pipeline input step, 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

Pipeline: Input Step Plugin 451.vf1a_a_4f405289 and earlier does not restrict or sanitize the optionally specified ID of the `input` step. This ID is used for the URLs that process user interactions for the given `input` step (proceed or abort) and is not correctly encoded. This allows attackers able to configure Pipelines to have Jenkins build URLs from `input` step IDs that would bypass the CSRF protection of any target URL in Jenkins when the `input` step is interacted with. Pipeline: Input Step Plugin 456.vd8a_957db_5b_e9 limits the characters that can be used for the ID of `input` steps in Pipelines to alphanumeric characters and URL-safe punctuation. Pipelines with `input` steps having IDs with prohibited characters will fail with an error. This includes Pipelines that have already been started but not finished before Jenkins is restarted to apply this update. [Pipeline: Declarative Plugin](https://plugins.jenkins.io/pipeline-model-definition/) provides an `input` directive that is internally using the `input` step, and specifies a non-default ID if not user-defined. Pipeline: Declarative Plugin 2.2114.v2654ca_721309 and earlier may specify values incompatible with this new restriction on legal values: `input` directives in a `stage` use the stage name (which may include prohibited characters) and `input` directives in a `matrix` will use a value generated from the matrix axis values (which always includes prohibited characters). Administrators are advised to update Pipeline: Input Step Plugin and Pipeline: Declarative Plugin at the same time, ideally while no Pipelines are running.
