A vulnerability in Jenkins Script Security Plugin 1415.v9a_f9b_3a_c253d and earlier allows attackers who can define classpath entries to execute arbitrary code on the Jenkins controller JVM. This occurs because the plugin downloads a JAR file specified by URL twice, confirming approval on the first download and loading classpath entries from the second.
AI Analysis
Technical Summary
Jenkins Script Security Plugin versions 1415.v9a_f9b_3a_c253d and earlier contain a vulnerability (CVE-2026-92128) where the plugin downloads a JAR file specified by URL twice. The first download confirms the approval of the JAR, and the second download loads classpath entries from the JAR. This behavior allows attackers who can define classpath entries to execute arbitrary code within the Jenkins controller JVM context.
Potential Impact
Successful exploitation enables attackers with the ability to specify classpath entries to execute arbitrary code on the Jenkins controller JVM, potentially leading to full compromise of the Jenkins server. The CVSS 3.1 score is 7.5 (High), indicating a significant impact on confidentiality, integrity, and availability.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or patch links are provided in the available data. Until a patch is available, restrict the ability to define classpath entries to trusted users only.
