A vulnerability in Jenkins Script Security Plugin versions 1415.v9a_f9b_3a_c253d and earlier allows users with Overall/Administer permission to have classpath entries automatically approved when copying or updating item configurations via REST API or CLI. This can enable attackers who can define classpath entries to execute arbitrary code on the Jenkins controller JVM.
AI Analysis
Technical Summary
Jenkins Script Security Plugin versions 1415.v9a_f9b_3a_c253d and earlier 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 the REST API or CLI. This automatic approval can be exploited by attackers able to define classpath entries to execute arbitrary code within the Jenkins controller JVM context. The vulnerability is tracked as CVE-2026-92127 and has a CVSS 3.1 score of 8.0, indicating high severity.
Potential Impact
Successful exploitation allows attackers with the ability to define classpath entries and Overall/Administer permissions to execute arbitrary code on the Jenkins controller JVM, potentially leading to full compromise of the Jenkins server and its 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 configuration changes closely. Avoid using REST API or CLI to update item configurations unless necessary and secure these interfaces appropriately.
