CVE-2025-53678
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 User1st uTester Plugin 1.1 and earlier stores the uTester JWT token unencrypted in its global configuration file on the Jenkins controller, where it can be viewed by users with access to the Jenkins controller file system.
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 User1st uTester Plugin versions 1.1 and earlier stores the uTester JWT authentication token in plaintext within its global configuration file on the Jenkins controller. Users with filesystem access to the Jenkins controller can directly read this configuration file and obtain the sensitive JWT token.

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 User1st uTester plugin is installedNavigate to Manage Jenkins > Manage Plugins > Installed and search for 'User1st uTester' or 'Utester' to confirm the plugin is present. Note the installed version.Affected if Plugin version 1.1 or earlier is installed
-
Locate the plugin configuration fileThe plugin stores its configuration in the Jenkins global configuration directory, typically under $JENKINS_HOME/org.jenkinsci.plugins.uter* or within the main jenkins.xml/GlobalConfig.xml. Use Jenkins script console to find: println(jenkins.model.Jenkins.instance.pluginManager.plugins.find{it.shortName=='uter'}.configDir)Affected if Plugin is installed - configuration file exists on filesystem
-
Read the configuration file for plaintext tokenOpen the configuration file using filesystem access and search for fields containing 'JWT', 'token', or 'uter' authentication credentials. Look for long alphanumeric strings that resemble JWT tokens (typically three base64-encoded sections separated by dots).Affected if Plaintext JWT token string is found directly in the configuration file content without encryption or masking
Environment is affected if the User1st uTester plugin version 1.1 or earlier is installed and a plaintext JWT token is present in the plugin's configuration file accessible via filesystem access.
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.
dbcve · scopedUpgrade to a patched version of the plugin when available, or migrate the token storage to use Jenkins' built-in credentials storage mechanism with encryption.
Version 1.2 or later (verify latest available version in Jenkins Plugin Index)
- 1. Back up your Jenkins configuration before making any changes
- 2. Navigate to Manage Jenkins > Manage Plugins > Installed
- 3. Locate the User1st uTester plugin in the list
- 4. Check for available updates and upgrade to the latest version
- 5. After upgrade, verify the plugin configuration stores the JWT token encrypted
- 6. Confirm the global configuration file (typically in $JENKINS_HOME/org.jenkinsci.plugins.utester.config.xml) now contains encrypted token data
