CVE-2022-36902
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 Dynamic Extended Choice Parameter Plugin 1.0.1 and earlier does not escape several fields of Moded Extended Choice parameters, resulting in a stored cross-site scripting (XSS) vulnerability exploitable by attackers with Item/Configure permission.
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 Dynamic Extended Choice Parameter Plugin versions 1.0.1 and earlier fail to properly escape HTML/script content in multiple fields of Moded Extended Choice parameters, allowing stored XSS attacks. Attackers with Item/Configure permission can inject malicious scripts that execute when other users view the configured parameters.

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.
-
Confirm plugin is installedNavigate to Manage Jenkins > Manage Plugins > Installed tab and search for 'Dynamic Extended Choice Parameter', or query the plugin manager via REST: /pluginManager/api/json?tree=plugins[shortName,version]Affected if The plugin appears in the installed plugins list
-
Check plugin versionIn the Installed plugins tab, locate the Dynamic Extended Choice Parameter plugin and read the Version columnAffected if Version is 1.0.1 or earlier (the version number is less than or equal to 1.0.1)
-
Identify jobs with Moded Extended Choice parametersBrowse each job's configuration (job > Configure) and look for parameter definitions named 'Moded Extended Choice', or search job config.xml files for elements containing 'ModedExtendedChoiceParameterDefinition' or parameters that include a 'mode' attributeAffected if Any job is configured with Moded Extended Choice parameter type
-
Examine Moded Extended Choice parameter configurationsFor each job with Moded Extended Choice parameters, review the parameter fields (such as Groovy Script, Default Value, or Description) for unsanitized HTML content like <script>, <img onerror=>, javascript:, or other suspicious markupAffected if Moded Extended Choice parameters contain raw HTML or script tags in their configuration values
The environment is affected if the Dynamic Extended Choice Parameter plugin is installed at version 1.0.1 or earlier AND jobs are configured with Moded Extended Choice parameters containing unsanitized content.
