Where this sits among everything scored
Real-World Exposure
io.jenkins.plugins:screenrecorderReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects Maven packages — download data is not available via public APIs for these ecosystems.
Description
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 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 configured are unaffected.

Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for io.jenkins.plugins:screenrecorder, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Remediation status
The records we use list no patched version of io.jenkins.plugins:screenrecorder for CVE-2022-43433. Check the maintainer's advisory, and where your build allows, override or pin the dependency away from the vulnerable range.
Mitigate without a patch
Escape or sanitise the affected output on the server side rather than relying on client-side filtering, and add a Content-Security-Policy that blocks inline script execution so injected markup cannot run even if it reaches the page.
