CVE-2026-92124: Vulnerability in Jenkins Project Jenkins Script Security Plugin
Jenkins Script Security Plugin 1415.v9a_f9b_3a_c253d and earlier checks the operations Groovy will perform with the elements it reads from a collection that a sandboxed script casts to another type but performs the cast on the collection itself, allowing attackers with permission to define and run sandboxed scripts, including Pipelines, to bypass the sandbox protection and execute arbitrary code in the context of the Jenkins controller JVM.
AI Analysis
Technical Summary
Jenkins Script Security Plugin versions up to 1415.v9a_f9b_3a_c253d contain a vulnerability where the plugin incorrectly checks operations performed by Groovy scripts on collections that are cast to other types. This flaw allows attackers who have permission to define and run sandboxed scripts, including Pipeline scripts, to bypass the sandbox restrictions and execute arbitrary code within the Jenkins controller JVM context.
Potential Impact
An attacker with permission to run sandboxed scripts can exploit this vulnerability to execute arbitrary code on the Jenkins controller JVM, potentially compromising the entire Jenkins server environment. This could lead to unauthorized control over the Jenkins instance and its resources.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict permissions to run sandboxed scripts to trusted users only and monitor for suspicious activity related to script execution.
