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
Jenkins FindBugs Plugin 5.0.0 and earlier does not escape the annotation message in tooltips, resulting in a stored cross-site scripting (XSS) vulnerability exploitable by attackers able to provide report files to Jenkins FindBugs Plugin's post build step.

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

Jenkins FindBugs Plugin versions 5.0.0 and earlier fails to properly escape annotation messages displayed in tooltips, allowing stored XSS injection. Attackers who can supply report files to the plugin's post-build step can embed malicious JavaScript that executes when users view the affected tooltips.

MitigationUpgrade to a version newer than 5.0.0 which includes proper output escaping. If upgrade is not immediately feasible, restrict or validate report file inputs to the FindBugs post-build step.

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. Confirm FindBugs plugin is installed
    Navigate to Manage Jenkins > Manage Plugins > Installed and search for FindBugs in the list of installed plugins
    Affected if FindBugs plugin appears in the installed plugins list
  2. Check installed FindBugs plugin version
    In the installed plugins list, locate FindBugs and note the version number displayed. Compare this version to the affected range: 5.0.0 and earlier
    Affected if The installed version is 5.0.0 or any version lower than 5.0.0
  3. Identify if FindBugs post-build step is configured
    Open a Jenkins job configuration that uses FindBugs. Look under Post-Build Actions for 'Publish FindBugs analysis report' or similar FindBugs-related post-build steps
    Affected if A FindBugs post-build action is configured to publish analysis reports
  4. Determine if report files can be supplied by untrusted users
    Review job configuration and overall Jenkins permissions to check whether users without admin privileges can trigger builds or supply custom report files to the FindBugs post-build step
    Affected if Untrusted or low-privilege users can supply or influence the report files processed by the FindBugs plugin

A user is affected if the FindBugs plugin is installed at version 5.0.0 or earlier AND a FindBugs post-build step is configured AND untrusted users can supply report files to that step.

Interim mitigation

Upgrade to a version newer than 5.0.0 which includes proper output escaping. If upgrade is not immediately feasible, restrict or validate report file inputs to the FindBugs post-build step.
