Machine-written summary

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

Jenkins SAML Plugin version 4.583.vc68232f7018a_ and earlier, as Maven package org.jenkins-ci.plugins:saml, does not implement a replay cache. An attacker who can obtain information about the SAML authentication flow between a user's browser and Jenkins can replay those requests and authenticate to Jenkins as that user. Upgrade to version 4.583.585.v22ccc1139f55, which implements a replay cache that rejects replayed requests.
