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

AI risk analysis

Summary: The flaw allows attackers with Overall/Administer permissions to automatically approve classpath entries, enabling them to execute arbitrary code in the Jenkins controller JVM.
Exploitability: Exploitation is relatively easy for attackers with Overall/Administer permissions, as they can copy or update item configurations through the REST API or CLI.
Blast radius: If exploited, the impact is high, as it allows arbitrary code execution in the context of the Jenkins controller JVM, 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 automatically approves the classpath entries in an item configuration when a user with Overall/Administer permission copies the item, or updates that configuration through the REST API or CLI, allowing attackers able to define classpath entries to execute arbitrary code in the context of the Jenkins controller JVM.
