CVE-2026-92129 Jenkins Project CVE debrief

Who should care

Jenkins administrators and users who define and run sandboxed scripts, including Pipelines, should assess their exposure to this vulnerability and take steps to mitigate it. This includes patching the Jenkins Script Security Plugin to version 1416.v9a_f9b_3a_c253d or later, restricting access to Jenkins to only trusted users, and monitoring Jenkins logs for suspicious activity. Additionally, defenders should prioritize patching or mitigating this漏洞, Def.

Why it matters

CVE-2026-92129 is a high-severity vulnerability in the Jenkins Script Security Plugin that allows attackers to bypass sandbox protection and execute code outside the sandbox. Defenders should prioritize patching or mitigating this vulnerability, especially in environments where Jenkins is used for continuous integration and continuous deployment (CI/CD) pipelines.

• Potential code execution outside the sandbox
• Bypassing of sandbox protection
• Elevation of privileges for attackers with script permissions

Technical summary

The Jenkins Script Security Plugin does not check calls from sandboxed scripts to methods added dynamically to a class at runtime, allowing attackers with permission to define and run sandboxed scripts to bypass the sandbox protection and execute code outside the sandbox. This vulnerability is a result of the plugin's failure to properly validate method calls from sandboxed scripts, which can lead to code execution outside the sandbox. The vulnerability has a significant impact on Jenkins administrators and users who define and run sandboxed scripts, including Pipelines.

Defensive priority

Defenders should prioritize patching or mitigating this vulnerability, especially in environments where Jenkins is used for continuous integration and continuous deployment (CI/CD) pipelines.

Recommended defensive actions

• Patch Jenkins Script Security Plugin to version 1416.v9a_f9b_3a_c253d or later
• Restrict access to Jenkins to only trusted users
• Monitor Jenkins logs for suspicious activity
• Implement additional security measures, such as network segmentation and intrusion detection
• Conduct regular security audits and vulnerability assessments
• Review and update incident response plans to ensure readiness
• Verify the integrity of Jenkins configurations and scripts
