AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:L/A:H
PR:H confirmed by description; S:C and I:H reflect that arbitrary command execution on the bastion control node inherently extends impact to all managed downstream assets, making I:L implausible.

Lifecycle Timeline

JumpServer is an open source bastion host and an operation and maintenance security audit system. Prior to 4.10.17, an authenticated administrator with Applet Host management and deployment permissions can inject Jinja2 expressions into the IP/Host field or Core Service Address field, causing Ansible to evaluate ansible_host inventory data or playbook variables during Applet Host deployment and execute arbitrary commands on the JumpServer control node. This issue is fixed in version 4.10.17.
AnalysisAI
Server-side template injection in JumpServer prior to 4.10.17 enables an authenticated administrator with Applet Host management and deployment permissions to plant Jinja2 expressions in the IP/Host or Core Service Address fields, which Ansible then evaluates as live template expressions during Applet Host deployment, yielding arbitrary OS command execution on the JumpServer control node. The patch was released in v4.10.17, confirmed via the GitHub release tag, and no public exploit code or CISA KEV entry has been identified at time of analysis. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires an active JumpServer account with administrator-level privileges and specifically the 'Applet Host management and deployment' permission assigned. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | CVSS 6.7 with PR:H correctly reflects that exploitation is gated behind a high-privilege account with specific Applet Host deployment permissions, which substantially reduces the attack surface compared to unauthenticated or low-privilege flaws. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | A JumpServer administrator with Applet Host deployment rights navigates to the Applet Host management interface and submits a crafted IP/Host value containing a Jinja2 payload such as a subprocess invocation or file-write expression. When the administrator then triggers deployment, Ansible parses the inventory data containing the injected field and evaluates the template expression in the context of the JumpServer service account, executing the embedded command on the control node. … |
| Remediation | Upgrade JumpServer to version 4.10.17 or later; this is the vendor-confirmed fix and is available at https://github.com/jumpserver/jumpserver/releases/tag/v4.10.17. … Detailed patch versions, workarounds, and compensating controls in full report. |
