Overview

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

Affected versions of this package are vulnerable to Improper Restriction of Rendered UI Layers or Frames when it doesn't serve the X-Frame-Options: deny HTTP header on REST API responses. Exploiting this vulnerability is possible by routing the victim through a specially crafted web page that embeds a REST API endpoint in an iframe and tricking the user into performing an action that would allow the attacker to learn the content of that REST API endpoint.
