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 · unedited
A cross-site request forgery (CSRF) vulnerability in Jenkins Nexus Platform Plugin 3.18.0-03 and earlier allows attackers to connect to an attacker-specified HTTP server using attacker-specified credentials IDs obtained through another method, capturing credentials stored in Jenkins.

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 confidence

A CSRF vulnerability in Jenkins Nexus Platform Plugin 3.18.0-03 and earlier allows authenticated attackers to trick administrators into making requests that connect to attacker-controlled HTTP servers using credential IDs stored in Jenkins, enabling credential capture.

MitigationUpgrade the Nexus Platform Plugin to a version newer than 3.18.0-03. Additionally, ensure global Jenkins CSRF protection is enabled to help mitigate such attacks.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Check Nexus Platform Plugin version
    Navigate to Manage Jenkins > Manage Plugins > Installed tab and search for 'Nexus Platform'. Verify the installed version in the list.
    Affected if Version is 3.18.0-03 or earlier
  2. Verify credentials exist in Jenkins
    Navigate to Manage Jenkins > Manage Credentials and check if any credentials (particularly Nexus-related credentials) are stored in Jenkins.
    Affected if Credentials are stored and the plugin version is vulnerable
  3. Check CSRF protection status
    Navigate to Manage Jenkins > Configure Global Security and locate the CSRF Protection section. Verify whether it is enabled or disabled.
    Affected if CSRF protection is disabled and the plugin version is vulnerable (though protection may still be bypassed)

Your environment is affected if the Nexus Platform Plugin version is 3.18.0-03 or earlier and you have credentials configured in Jenkins that the plugin can access.

Generated from the published advisory. Verify against your own configuration.

Check your environment

Paste your version and any relevant configuration and it will be compared against the affected criteria above. Do not include secrets or credentials.

AI-assisted, checked against the advisory. Informational, not a guarantee.

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 data
Upgrade available Upgrade to a release after 3.18.0-03
Interim mitigation

Upgrade the Nexus Platform Plugin to a version newer than 3.18.0-03. Additionally, ensure global Jenkins CSRF protection is enabled to help mitigate such attacks.
