CVE-2026-92127: Vulnerability in Jenkins Project Jenkins Script Security Plugin
Jenkins Script Security Plugin 1415.v9a_f9b_3a_c253d and earlier automatically approves the classpath entries in an item configuration when a user with Overall/Administer permission copies the item, or updates that configuration through the REST API or CLI, allowing attackers able to define classpath entries to execute arbitrary code in the context of the Jenkins controller JVM.
AI Analysis
Technical Summary
Jenkins Script Security Plugin versions up to and including 1415.v9a_f9b_3a_c253d contain a vulnerability where classpath entries in an item configuration are automatically approved if a user with Overall/Administer permission copies the item or updates the configuration through REST API or CLI. This behavior allows attackers with the ability to define classpath entries to execute arbitrary code in the context of the Jenkins controller JVM, potentially compromising the Jenkins server.
Potential Impact
Attackers able to define classpath entries and with Overall/Administer permissions can execute arbitrary code on the Jenkins controller JVM. This could lead to full compromise of the Jenkins server environment.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict Overall/Administer permissions to trusted users only and monitor for suspicious configuration changes.
