A persisted cross-site scripting vulnerability exists in Jenkins Badge Plugin 1.4 and earlier in BadgeSummaryAction.java, HtmlBadgeAction.java that allows attackers able to control build badge content to define JavaScript that would be executed in another user's browser when that other user performs some UI actions.

Security readout for executives and security teams

Plain-English summary

This is a stored cross-site scripting issue in Jenkins Badge Plugin 1.4 and earlier. Someone who can control build badge content could cause JavaScript to run in another Jenkins user's browser during certain UI interactions. The main business risk is compromise of Jenkins user sessions or trusted workflow context.

Executive priority

Treat this as a targeted Jenkins hardening item, not an internet-wide emergency based on available evidence. Prioritize environments where Jenkins is business-critical, broadly accessible, or allows many users to modify build output shown in the UI.

Technical view

CVE-2018-1000604 affects Jenkins Badge Plugin 1.4 and earlier in BadgeSummaryAction.java and HtmlBadgeAction.java. The issue is persisted XSS through attacker-controlled build badge content, executed in another user's browser when that user performs some UI actions. No CVSS, CWE, or explicit fixed version is provided in the source bundle.

Likely exposure

Exposure is likely limited to Jenkins environments using Badge Plugin 1.4 or earlier, especially where non-administrators, jobs, or automation can influence build badge content. Systems without this plugin, or without attacker control over badge content, are not indicated as exposed by the provided sources.

Exploitation context

The source bundle describes required attacker control over build badge content and victim interaction in the Jenkins UI. It does not cite active exploitation, public exploit use, KEV listing, or weaponized details. Active exploitation should not be assumed from the provided evidence.

Researcher notes

The affected code paths named are BadgeSummaryAction.java and HtmlBadgeAction.java. The key condition is attacker control of persisted badge content. The bundle lacks CVSS, CWE mapping, affected CPEs, exploit evidence, and explicit fixed-version details, so validation should stay close to Jenkins advisory data.

Mitigation direction

  • Check Jenkins SECURITY-906 and plugin guidance for the fixed Badge Plugin version.
  • Update or remove Badge Plugin after confirming vendor-supported remediation.
  • Restrict who can configure jobs or content that influences build badges.
  • Review Jenkins permissions for untrusted contributors and automation accounts.
  • Consider disabling badge functionality until remediation is confirmed.

Validation and detection

  • Inventory Jenkins controllers for Badge Plugin version 1.4 or earlier.
  • Identify jobs or users able to control build badge content.
  • Review recent badge content for unexpected HTML or script-like entries.
  • Confirm remediation status against Jenkins SECURITY-906 guidance.
  • Verify permissions limit badge content control to trusted users.
