CVE-2015-5321
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 · uneditedThe sidepanel widgets in the CLI command overview and help pages in Jenkins before 1.638 and LTS before 1.625.2 allow remote attackers to obtain sensitive information via a direct request to the pages.
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 sidepanel widgets in Jenkins CLI command overview and help pages before versions 1.638 and LTS 1.625.2 expose sensitive information to remote attackers via direct requests to these pages. This is an information disclosure vulnerability where unauthenticated users can access the sidepanel content that should be restricted.

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.
-
Identify the Jenkins versionNavigate to Manage Jenkins > About Jenkins or check the jenkins.war file version. On Linux, run: java -jar jenkins.war --versionAffected if The installed version is 1.637 or earlier, or LTS 1.625.1 or earlier
-
Verify if anonymous read access is enabledNavigate to Manage Jenkins > Configure Global Security. Under Authorization, check if 'Anyone can do anything' or 'Anonymous read access' is selected.Affected if Anonymous users have any level of read or full access to Jenkins
-
Test access to CLI help pages without authenticationOpen a browser in incognito mode and navigate to: http://your-jenkins-host:8080/cli/help. Also try accessing the sidepanel directly via any /cli/ URLs while logged out.Affected if The pages load and display content without requiring login credentials
-
Check for sensitive information in CLI overviewAccess the CLI command overview page (typically at /cli/) as an anonymous user and inspect whether job names, build histories, or configuration details are visible in the sidepanel widgets.Affected if Unauthenticated users can view sidepanel content containing job names, build logs, or other sensitive data
A defender is affected if running Jenkins version 1.637 or earlier (or LTS 1.625.1 or earlier) AND anonymous users can access the CLI help or overview pages and view sidepanel content that should require authentication.
