How to Fix CVE-2022-43433

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

io.jenkins.plugins:screenrecorder fixed: Latest secure release 
<dependency>
    <groupId>io.jenkins.plugins</groupId>
    <artifactId>screenrecorder</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=io.jenkins.plugins

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2022-43433, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=io.jenkins.plugins

Analyze the terminal output to locate any version of Screenrecorder 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=io.jenkins.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-693: Protection Mechanism Failure, where the product does not use or incorrectly uses a protection mechanism that provides sufficient defense against directed attacks against the product. In Screenrecorder, 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

Jenkins sets the `Content-Security-Policy` header to static files served by Jenkins (specifically `DirectoryBrowserSupport`), such as workspaces, `/userContent`, or archived artifacts, unless a Resource Root URL is specified. ScreenRecorder Plugin 0.7 and earlier programmatically updates [the Java system property](https://www.jenkins.io/doc/book/managing/system-properties/#hudson-model-directorybrowsersupport-csp) allowing administrators to customize the `Content-Security-Policy` header for static files served by Jenkins to include `media-src: 'self'`. On a Jenkins instance with default configuration, this effectively disables all other directives in the default rule set, including `script-src`. This allows cross-site scripting (XSS) attacks by users with the ability to control files in workspaces, archived artifacts, etc. Jenkins instances with [Resource Root URL](https://www.jenkins.io/doc/book/security/user-content/#resource-root-url) configured are unaffected.
