Bug ID: 1434338 Summary: CVE-2017-2651 jenkins-mailer-plugin: Emails were sent to addresses not associated with actual users of Jenkins by Mailer Plugin Product: Security Response Component: vulnerability Keywords: Security Severity: medium Priority: medium Assignee: security-response-team@redhat.com Reporter: amaris@redhat.com CC: bleanhar@redhat.com, ccoleman@redhat.com, dedgar@redhat.com, dmcphers@redhat.com, java-sig-commits@lists.fedoraproject.org, jgoulding@redhat.com, jkeck@redhat.com, joelsmith@redhat.com, kseifried@redhat.com, mizdebsk@redhat.com, msimacek@redhat.com, msrb@redhat.com, tdawson@redhat.com
The Mailer and Email Extension Plugins are able to send emails to a dynamically created list of users based on the changelogs, like authors of SCM changes since the last successful build.
This could in some cases result in emails being sent to people who have no user account in Jenkins, and in rare cases even people who were not involved in whatever project was being built, due to some mapping based on the local-part of email addresses.
Affected versions: up to and including version 1.19
