This critical-severity CVE scores 9.9 under NVD CVSS v3. EPSS exploit probability: 1.7%, top 25% of all CVEs by exploit prediction. 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. An authenticated user can exploit a vulnerability in MongoDB sessions to execute arbitrary commands, leading to remote code execution. This vulnerability may further be leveraged to gain root privileges on the system. Through the WEB CLI interface provided by the koko component, a user logs into the authorized mongoDB database and exploits the MongoDB session to execute arbitrary commands. This vulnerability has been addressed in versions 2.28.20 and 3.7.1. Users are advised to upgrade. There are no known workarounds for this vulnerability.
