All stable versions of jetty are actively supported for security issues. Deprecated versions may be supported for serious security issues or on a commercial support basis.

Do not open a public issue to report a security vulnerability. Please send a message to [email protected] and we will create a private issue in which the issue can be triaged and handled.

The following checklist is used to handle security issues:

• On receipt of a security report via [email protected] or other channels, if it cannot be trivially dismissed (already fixed, known not a problem, etc.), then a Github security advisory is created by project leadership.
• Copy this list as a markdown in the security advisory for tracking the completion of various tasks.
• Jetty committers and the reporters are added to the security advisory. Individual committers can also be named in the comments for addition.
• Initial triage and discussion are performed in the comments of the advisory.
• If enough information exists to attempt reproduction or fix, then a private repository is created as part of the GitHub security advisory.
• If the vulnerability cannot be confirmed then close the security advisory, else continue.
• Generate a CVE score and add it to the advisory description.
• Identify a CWE Definition and add it to the advisory description.
• Identify vulnerable version(s), including current and past versions that are affected (e.g. 9.4.0 through 9.4.35, and 10.0.0.alpha1 through 10.0.0.beta3…​etc.)
• Identify and document workaround(s), if applicable, in the comments of the security advisory.
• Open an Gitlab@Eclipse EMO CVE issue to have a CVE allocated.
  The issue should be opened under the "Eclipse Foundation" > "EMO Team" > "EMO" section as a "cve" description, with the "This issue is confidential" checkbox checked.
  Follow the template for what details are necessary to file for a CVE.
• Once the CVE is allocated update the Security Advisory with the number
• Build and test fix(es) locally and in CI environment.
• Merge tests and fix - ensure description does not mention vulnerability directly. Do not merge directly from the security advisory as it can be traced back before publication.
• Build and stage release candidate.
• Notify interested parties of pending security advisory and staged release:
  1. Include CVE number, CVE score, and CWE
  2. Include Workarounds
  3. Stress that it is confidential
  4. Advise the security advisory will be published in 2 days unless they indicate they need more time.
• If testing is OK, then the release is promoted.
• Interested parties are notified of the availability of release on Maven Central.
• Publish security advisory and CVE publicly.
• Edit VERSION.txt and so that the CVE number is now recorded against merged PR.
• Edit the release(s) on Github to identify CVE number that was addressed/resolved.
• Update downstream images (Docker, etc.).
• Update project website with new security entry.
• Review security processes & completion.
