CVE-2020-2181
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 Credentials Binding Plugin 1.22 and earlier does not mask (i.e., replace with asterisks) secrets in the build log when the build contains no build steps.
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 Credentials Binding Plugin versions 1.22 and earlier fails to mask secrets (replace with asterisks) in build logs when a build contains no build steps. This causes sensitive credentials to be exposed in plaintext within build logs, potentially allowing unauthorized users with log access to retrieve credentials.

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.
-
Check Credentials Binding Plugin versionNavigate to Manage Jenkins > Manage Plugins > Installed tab and look for 'Credentials Binding Plugin' in the list to see its version number, or use the Jenkins CLI: java -jar jenkins-cli.jar list-plugins credentials-bindingAffected if The installed version is 1.22 or earlier
-
Identify jobs using credentials with no build stepsReview job configurations in Jenkins to find jobs that have credential bindings configured but have no build steps defined (or only have post-build actions)Affected if Jobs exist that bind credentials but contain zero build steps
-
Examine build logs for exposed secretsNavigate to a completed build of a job with credentials but no build steps, access the build console output (Build History > Console Output), and search for any plaintext credential values that should have been masked with asterisksAffected if Plaintext credential values appear in the console output instead of masked values like '******'
A user is affected if the Credentials Binding Plugin version is 1.22 or earlier AND there are builds with credentials bound but no build steps, where plaintext secrets appear in build logs.

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 Jenkins Credentials Binding Plugin to version 1.23 or later, which contains the fix to ensure secrets are properly masked even when builds contain no build steps.
