CVE-2026-92123

8.8 HIGH

Published 2026-09-16 · Updated 2026-09-21

AI risk analysis

Summary: The flaw allows attackers to bypass sandbox protection by performing operations on a null receiver, enabling the execution of arbitrary code in the Jenkins controller JVM.
Exploitability: Exploitation requires permission to define and run sandboxed scripts, making it moderately difficult. Precondition is the presence of the vulnerable Jenkins Script Security Plugin version.
Blast radius: If exploited, the impact is high, as it could lead to full compromise of the Jenkins controller JVM and execution of arbitrary code.
Detection: No reliable host or network indicator is derivable from the published description.
Prioritized remediation: Upgrade to Jenkins Script Security Plugin 1415.v9a_f9b_3a_c253d or later.

NVD description

Jenkins Script Security Plugin 1415.v9a_f9b_3a_c253d and earlier does not intercept operations performed on a null receiver (method calls, property and attribute accesses, and array accesses), 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.
