CVE-2026-57282 Jenkins Project CVE debrief

Who should care

Defenders responsible for Jenkins deployments should assess exposure and potential impact based on workspace directory name control and implement compensating controls to monitor and limit potential impacts. This includes verifying the version of Jenkins Git client Plugin, reviewing compensating controls for exposed systems, and tracking exceptions and remediation efforts.

Why it matters

CVE-2026-57282 allows attackers to execute arbitrary operating system commands on Jenkins agent systems. Defenders should verify exposure, assess potential impact, and implement compensating controls.

• Verify exposure based on workspace directory name control.
• Assess potential impact on Jenkins agent systems.
• Implement compensating controls to monitor and limit potential impacts.

Technical summary

The Jenkins Git client Plugin 6.6.0 and earlier does not correctly escape the workspace directory name when embedded into a generated SSH wrapper script, allowing attackers able to control the name of a build's working directory to execute arbitrary operating system commands on the agent. This vulnerability allows for potential exploitation through command injection, emphasizing the need for defenders to verify exposure and assess potential impact based on workspace directory name control and implement compensating controls.

Defensive priority

Defenders should prioritize verifying exposure and assessing potential impact.

Recommended defensive actions

• Verify the version of Jenkins Git client Plugin is 6.6.1 or later.
• Assess exposure based on the workspace directory name control.
• Implement compensating controls to monitor and limit potential impacts.
• 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.
• Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up.
