Machine-written summary

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

Jenkins Multijob Plugin versions before 669.v9d96a (including 662.vd2e0001f6b_b_d and earlier) have a cross-site request forgery vulnerability because an HTTP endpoint does not require POST requests. An attacker who can get a logged-in user to visit a malicious web page can cause failed Multijob builds to resume. Upgrade to version 669.v9d96a or later, which requires POST requests for the affected endpoint.
