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 Extensible Choice Parameter plugin is installedNavigate to Jenkins > Manage Jenkins > Manage Plugins > Installed tab, or use the Jenkins CLI/API to list installed plugins. Search for 'Extensible Choice Parameter' in the plugin list.Affected if The plugin is not found in the installed plugins list, meaning the vulnerability does not apply.
-
Determine the installed version of the pluginIn the Manage Plugins > Installed tab, locate the Extensible Choice Parameter plugin and note the version number displayed in the 'Version' column.Affected if The version number cannot be determined or is not visible in the plugin management interface.
-
Compare the installed version against the affected rangeCompare the installed version to 239.v5f5c278708cf. Any version less than or equal to 239.v5f5c278708cf is affected.Affected if The installed version is 239.v5f5c278708cf or any earlier version (e.g., 238.v..., 237.v..., etc.).
-
Identify if users have permission to configure the pluginReview Jenkins role-based access control (RBAC) or matrix authorization settings to determine which authenticated users can access the Extensible Choice Parameter plugin configuration pages (typically under job parameter configuration).Affected if The vulnerability requires an authenticated user with permissions to configure choice parameters; however, the CSRF nature means any authenticated user could be targeted.
You are affected if the Extensible Choice Parameter plugin is installed and its version is 239.v5f5c278708cf or any earlier version.
