Overview

org.jenkins-ci.main:jenkins-core is an open source automation server.

Affected versions of this package are vulnerable to Cross Site Request Forgery (CSRF). CSRF tokens in older releases of did not expire, thereby allowing attackers able to obtain them to bypass CSRF protection. By default, CSRF tokens only validated user authentication access and IP address. This could allow attackers the ability to obtain a CSRF token for another user to implement CSRF attacks as long as the victim’s IP address remained unchanged.
