AI risk analysis

Summary: The flaw allows attackers to execute arbitrary code outside the sandbox by exploiting @Builder annotations, posing a significant security risk.
Exploitability: Exploitation requires permission to define and run sandboxed scripts and the presence of a suitable class on the classpath, making it moderately difficult.
Blast radius: If exploited, the impact could be severe, as it allows execution of code outside the sandbox, potentially leading to full system compromise.
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 reject @Builder annotations whose builderStrategy member names an arbitrary class, allowing attackers with permission to define and run sandboxed scripts, including Pipelines, to execute code outside the sandbox if a suitable class is present on the classpath of the component that evaluates the script.
