Follow Jenkins advisories by subscribing to the jenkinsci-advisories mailing list or the advisories RSS feed, and by watching the notices Jenkins shows administrators inside the app. Then triage each advisory against your installed core and plugin versions the same week it appears.
Where advisories come from
The Jenkins project publishes advisories as the primary public notice for issues in Jenkins and its plugins. Each new one is announced in four places:
| Channel | Notes |
|---|---|
| jenkinsci-advisories group | Email with a short overview and a link. Only the security team can post |
| oss-security mailing list | Excerpts of the advisory |
| RSS feed | Available at /security/advisories/rss.xml on the Jenkins site |
| In Jenkins notices | Shown to administrators running affected versions of core or plugins |
Jenkins also acts as a CVE Numbers Authority and submits CVE metadata at the same time as each advisory. To join the group, email jenkinsci-advisories+subscribe@googlegroups.com.
A weekly triage routine
- Collect. Check the feed, the mailbox and the plugin manager warnings.
- Match. Compare each advisory to your inventory of core version and plugin versions.
- Assess exposure. Is the affected feature enabled? Who can reach it? Is the controller on the internet?
- Decide. Update, apply a workaround, restrict access, or stop using the plugin.
- Record. Note the advisory, your decision, who owns it and the date.
- Verify. After updating, confirm the new version and that the warning cleared.
What the project does not promise
The Jenkins security page says the project aims to fix all vulnerabilities in core and plugins in a timely manner, but cannot guarantee it, because of the number and variety of plugins and the autonomy of maintainers. That is why your own inventory matters: you need to know which plugins you rely on and whether anyone still maintains them.
Keep an inventory ready
You cannot triage without a list. Keep plugin names and versions, the core version, the Java version and the agent versions in a file or system that is easy to search. Refresh it after each upgrade.
Try it yourself
The demo shows a zero day watch view: the feed, the match against what you run, and the decision.

Where Safeguard fits
Safeguard offers zero day discovery and dependency scanning, which helps match published issues to what you run. There is a free scan.
Quick check
Does Jenkins assign CVE identifiers?
Yes. The project acts as a CVE Numbers Authority and submits CVE metadata with each advisory.
Will Jenkins tell me inside the app?
Yes, administrators running affected versions see notifications for core and plugins.
