Machine-written summary

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

Jenkins Microsoft Entra ID (previously Azure AD) Plugin versions 666.v6060de32f87d and earlier do not restrict the redirect URL after login. An attacker can use this open redirect for phishing by getting a user to open a Jenkins URL that forwards them to another site after successful authentication. Upgrade to version 667.v4c5827a or later, which only redirects to relative Jenkins URLs.
