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… (CVE-2026-92129)
Jenkins Script Security Plugin versions 1415.v9a_f9b_3a_c253d and earlier do not properly check calls from sandboxed scripts to methods that are added dynamically to a class at runtime. This flaw allows attackers with permission to define and run sandboxed scripts, such as Pipelines, to bypass the sandbox protection and execute code outside the sandbox environment.
AI Analysis
Technical Summary
The vulnerability in Jenkins Script Security Plugin (CVE-2026-92129) arises because the plugin fails to verify calls from sandboxed scripts to dynamically added methods on classes at runtime. This allows users who can define and execute sandboxed scripts to circumvent sandbox restrictions and run arbitrary code outside the sandbox, potentially leading to full system compromise. The CVSS 3.1 score is 7.5 (High), reflecting network attack vector, high impact on confidentiality, integrity, and availability, and requiring low privileges but high attack complexity.
Potential Impact
An attacker with permission to run sandboxed scripts in Jenkins can exploit this vulnerability to bypass sandbox protections and execute arbitrary code outside the sandbox. This can lead to unauthorized code execution, potentially compromising the Jenkins server and its environment, impacting confidentiality, integrity, and availability of the system.
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 define and run sandboxed scripts to trusted users only to reduce risk.
