Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

The Jenkins SAML Single Sign On (SSO) Plugin (io.jenkins.plugins:miniorange-saml-sp) versions before 2.1.0 do not validate hostnames when connecting to miniOrange or the configured identity provider to retrieve SAML metadata. An attacker in a position to intercept network traffic, such as through a man-in-the-middle attack, could intercept these connections. Upgrade to version 2.1.0, which performs hostname validation.
