EchelonGraph scoreMEDIUM confidence

This medium-severity CVE scores 6.7 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.7% (52nd percentile of EPSS-scored CVEs). GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

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.
