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 Subversion Release Manager Plugin 1.2 and earlier does not escape the error message for the Repository URL field during form validation, resulting in a reflected cross-site scripting (XSS) vulnerability where malicious JavaScript can be injected via the URL field and executed in the victim's browser when validation fails.

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 Subversion Release Manager Plugin is installedNavigate to Jenkins > Manage Jenkins > Manage Plugins > Installed tab and search for 'Subversion Release Manager', or inspect the $JENKINS_HOME/plugins/ directory for a file named subversion-release-manager.jpi or subversion-release-manager/Affected if The plugin appears in the installed list or the plugin directory exists
-
Check installed plugin versionIn Jenkins UI, click on the Subversion Release Manager plugin entry in the Installed tab to view its version, or if you have file system access, examine the plugin's MANIFEST.MF file within $JENKINS_HOME/plugins/subversion-release-manager/Affected if The displayed version is 1.2 or earlier, or the version cannot be determined (implying it may be an unversioned release)
-
Confirm Jenkins user access to plugin configurationCheck if you have permission to access or configure a job that uses the Subversion Release Manager plugin, or attempt to navigate to a job configured with Subversion Release Manager and access its configuration pageAffected if You can access the plugin's configuration form where the Repository URL field is available for input
-
Verify Repository URL validation is accessibleIn a job using Subversion Release Manager, locate the Repository URL field in the configuration, enter a test URL, and save or apply the configuration to trigger validationAffected if The form submits and validation error messages are displayed (the vulnerability occurs during validation failure)
You are affected if the Subversion Release Manager Plugin version 1.2 or earlier is installed and you can trigger form validation that displays error messages for the Repository URL field.

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 dataUpgrade the Subversion Release Manager Plugin to a patched version that properly escapes error message output, or implement server-side input validation and output encoding for the Repository URL field before displaying validation errors.
