CVE-2020-2192
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 · uneditedA cross-site request forgery vulnerability in Jenkins Self-Organizing Swarm Plug-in Modules Plugin 3.20 and earlier allows attackers to add or remove agent labels.
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 confidenceThis is a CSRF vulnerability in Jenkins Self-Organizing Swarm Plug-in Modules Plugin versions 3.20 and earlier. The plugin fails to properly validate anti-CSRF tokens, allowing attackers to craft malicious requests that trick authenticated users into adding or removing agent labels on Jenkins nodes.

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 Swarm Plug-in Modules is installedNavigate to Jenkins > Manage Jenkins > Manage Plugins > Installed and search for 'Swarm Plug-in Modules' or 'self-organizing-swarm-mod'. Confirm the plugin appears in the list of installed plugins.Affected if The plugin is not installed, this CVE does not apply.
-
Check plugin version numberIn the Installed Plugins list, locate the Swarm Plug-in Modules entry and note the Version column. Compare this version against the affected range: versions 3.20 and earlier.Affected if Installed version is 3.20 or lower (for example, 3.20, 3.19, 3.18, etc.).
-
Confirm plugin is actively configuredNavigate to Jenkins > Manage Jenkins > Configure Global Security and review Swarm client configuration or any Swarm-related settings. Also check if any Swarm client configurations exist under node management or agent configurations.Affected if The plugin is installed but not actively configured or used, the exploit surface is reduced but the vulnerable code is still present.
-
Review Jenkins CSRF protection settingsGo to Jenkins > Manage Jenkins > Configure Global Security and locate the 'CSRF Protection' section. Check whether protection is enabled or disabled.Affected if CSRF protection is disabled, the exploit is fully functional. If enabled, the attack requires additional conditions but the vulnerable plugin still exists.
You are affected if the Swarm Plug-in Modules plugin is installed with version 3.20 or earlier, regardless of CSRF protection settings, since the plugin itself fails to validate anti-CSRF tokens.
Generated from the published advisory. Verify against your own configuration.
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 to plugin version 3.21 or later which includes CSRF protection. If immediate upgrade is not possible, ensure Jenkins global security settings enforce CSRF protection and restrict administrative access to trusted users only.
