CVE-2020-2269
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedJenkins chosen-views-tabbar Plugin 1.2 and earlier does not escape view names in the dropdown to select views, resulting in a stored cross-site scripting (XSS) vulnerability exploitable by attackers with the ability to configure views.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceThe Jenkins chosen-views-tabbar Plugin versions 1.2 and earlier fails to properly escape view names before rendering them in the dropdown menu used to select views. This allows an attacker with permissions to configure views to inject malicious JavaScript code that executes when other users view or interact with the view dropdown, resulting in a stored cross-site scripting (XSS) vulnerability.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Verify chosen-views-tabbar plugin is installedNavigate to Jenkins > Manage Jenkins > Manage Plugins > Installed, or check the file system for the plugin manifest at $JENKINS_HOME/plugins/chosen-views-tabbar/META-INF/MANIFEST.MFAffected if The plugin is present in the Jenkins instance
-
Determine the installed plugin versionRead the Plugin-Version from the manifest file at $JENKINS_HOME/plugins/chosen-views-tabbar/META-INF/MANIFEST.MF, or view the version in the Jenkins plugin manager UIAffected if The version is 1.2 or earlier (the affected range is <= 1.2)
-
Identify users with view configuration permissionsNavigate to Jenkins > Manage Jenkins > Manage and Assign Permissions. Check which users or groups have the 'Overall/Administer' permission versus lower-privileged permissions. Review view-level permissions in the security matrixAffected if Non-administrator users have permissions to configure or create views, as the attacker needs this access to inject malicious view names
-
Inspect existing views for unusual namesNavigate to the Jenkins home page, click the views dropdown, and review all view names for characters that could be used in XSS payloads (such as <script>, javascript:, onerror=, or unusual encoding)Affected if Any view names contain potentially malicious JavaScript content or unusual characters typical of XSS injection attempts
The environment is affected if the chosen-views-tabbar plugin version 1.2 or earlier is installed AND non-administrator users have view configuration permissions, creating conditions for stored XSS injection.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataUpdate the Jenkins chosen-views-tabbar Plugin to version 1.3 or later, which includes proper output encoding of view names. Until patched, restrict view configuration permissions to trusted administrators only.
