CVE-2026-70431: Vulnerability in Jenkins Project Jenkins Multijob Plugin
Jenkins Multijob Plugin 669.v9d96a_d9c71b_0 and earlier provides Groovy scripting features that do not integrate with Script Security Plugin, allowing attackers with Item/Create or Item/Configure permission to execute arbitrary code in the context of the Jenkins controller JVM.
AI Analysis
Technical Summary
The Jenkins Multijob Plugin up to version 669.v9d96a_d9c71b_0 provides Groovy scripting capabilities that bypass the Script Security Plugin. This lack of integration permits users who have Item/Create or Item/Configure permissions to run arbitrary code on the Jenkins controller JVM, potentially leading to unauthorized code execution.
Potential Impact
Attackers with certain permissions (Item/Create or Item/Configure) can execute arbitrary code on the Jenkins controller JVM. This could lead to full compromise of the Jenkins controller environment depending on the privileges of the Jenkins process.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict Item/Create and Item/Configure permissions to trusted users only to reduce risk.
