Details

As written in the advisory (Markdown source, shown as plain text).

Jenkins SAML Single Sign On(SSO) Plugin 2.0.2 and earlier does not perform hostname validation when connecting to miniOrange or the configured IdP to retrieve SAML metadata. This lack of validation could be abused using a man-in-the-middle attack to intercept these connections. SAML Single Sign On(SSO) Plugin 2.1.0 performs hostname validation when connecting to miniOrange or the configured IdP to retrieve SAML metadata.
