Foreman before 1.8.1 does not set the secure flag for the _session_id cookie in an https session, which makes it easier for remote attackers to capture this cookie by intercepting its transmission within an http session.
Forman before 1.7.4 does not verify SSL certificates for LDAP connections, which allows man-in-the-middle attackers to spoof LDAP servers via a crafted certificate.
Cross-site scripting (XSS) vulnerability in the template preview function in Foreman before 1.6.1 allows remote attackers to inject arbitrary web script or HTML via a crafted provisioning template.
Smart Proxy (aka Smart-Proxy and foreman-proxy) in Foreman before 1.5.4 and 1.6.x before 1.6.2 does not validate SSL certificates, which allows remote attackers to bypass intended authentication and execute arbitrary API requests via a request without a certificate.
