CVE-2026-92129: Vulnerability in Jenkins Project Jenkins Script Security Plugin
Jenkins Script Security Plugin 1415.v9a_f9b_3a_c253d and earlier does not check calls from sandboxed scripts to methods added dynamically to a class at runtime, allowing attackers with permission to define and run sandboxed scripts, including Pipelines, to bypass the sandbox protection and execute code outside the sandbox.
AI Analysis
Technical Summary
The Jenkins Script Security Plugin up to version 1415.v9a_f9b_3a_c253d does not properly check calls from sandboxed scripts to methods that are added dynamically to classes at runtime. This flaw enables attackers who have permission to define and run sandboxed scripts to bypass the sandbox restrictions and execute arbitrary code outside the sandbox environment, potentially leading to unauthorized code execution within Jenkins.
Potential Impact
Attackers with permission to run sandboxed scripts can bypass sandbox protections and execute code outside the sandbox. This could lead to unauthorized code execution within the Jenkins environment, potentially compromising the integrity and security of the Jenkins server and its pipelines.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance.
