CVE-2026-92125 Jenkins Project CVE debrief

Who should care

Jenkins administrators and users with permission to define and run sandboxed scripts should assess exposure and apply remediation. They should also review and restrict permissions for users who can define and run sandboxed scripts, and monitor Jenkins controller JVM for suspicious activity.

Why it matters

CVE-2026-92125 allows attackers with script permissions to execute arbitrary code, bypassing sandbox protections. Defenders should verify exposure, restrict script permissions, and monitor for suspicious activity.

• Potential code execution in the context of the Jenkins controller JVM
• Bypass of sandbox protection for scripts
• Elevation of privileges for attackers with script permissions

Technical summary

The Jenkins Script Security Plugin is vulnerable to arbitrary AST transformation execution. Attackers with permission to define and run sandboxed scripts can bypass the sandbox protection and execute arbitrary code in the context of the Jenkins controller JVM. This is due to the plugin not rejecting the @GroovyASTTransformationClass annotation. The vulnerability affects Jenkins Script Security Plugin versions up to 1415.v9a_f9b_3a_c253d. Defenders should prioritize verifying exposure and applying remediation for Jenkins Script Security Plugin versions up to 1415.v9a_f9b_3a_c253d.

Defensive priority

Defenders should prioritize verifying exposure and applying remediation for Jenkins Script Security Plugin versions up to 1415.v9a_f9b_3a_c253d.

Recommended defensive actions

• Verify Jenkins Script Security Plugin version and update to a fixed version if necessary
• Review and restrict permissions for users who can define and run sandboxed scripts
• Monitor Jenkins controller JVM for suspicious activity
• Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up
• Review compensating controls for exposed systems while remediation is scheduled and verified
• Check relevant monitoring, detection, and logs for exposed assets that need extra review
• Track exceptions, retest remediated assets, and close the item only after evidence is documented
