CVE-2023-30513
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 Kubernetes Plugin 3909.v1f2c633e8590 and earlier does not properly mask (i.e., replace with asterisks) credentials in the build log when push mode for durable task logging is enabled.
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 Kubernetes Plugin fails to properly mask credentials in build logs when push mode for durable task logging is enabled. This causes sensitive credentials to be exposed in plaintext within build logs, allowing unauthorized actors with log access to obtain 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 if Jenkins Kubernetes Plugin is installedNavigate to Manage Jenkins > Manage Plugins > Installed tab and look for 'Kubernetes' in the plugin list, or use the Jenkins CLI: java -jar jenkins-cli.jar list-plugins | grep kubernetesAffected if The Kubernetes plugin is not installed, then this CVE does not apply
-
Determine the installed version of the Kubernetes pluginIn the Installed Plugins tab, locate the Kubernetes plugin and note the Version column, or use: java -jar jenkins-cli.jar list-plugins kubernetesAffected if Version is 3909.v1f2c633e8590 or earlier, indicating the plugin is in the affected range
-
Check if push mode for durable task logging is enabledReview your Jenkins configuration files (typically in the job configuration XML or jenkins.yaml) for the durable-task log storage configuration, or check the Kubernetes pod template settings in the Kubernetes Cloud configuration for push-based logging settingsAffected if Push mode for durable task logging is enabled; this is the configuration that triggers the credential exposure flaw
-
Examine recent build logs for exposed credentialsAccess recent build logs via Jenkins UI (select a job > Builds > Console Output) or review log files stored in the workspace, searching for any plaintext strings that appear to be passwords, API keys, or other credential formatsAffected if Any sensitive credentials appear in plaintext in build logs, confirming active exploitation of this vulnerability
You are affected if the Jenkins Kubernetes Plugin version is 3909.v1f2c633e8590 or earlier AND push mode for durable task logging is enabled, resulting in potential credential exposure in build logs.
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 Jenkins Kubernetes Plugin to version 3915.v8867e3a_8e739 or later, or disable push mode for durable task logging if upgrading is not immediately feasible.
