CVE-2025-59954Public exploitNetwork attack vector

Authenticated command execution via unsafe XPath evaluation

Published Sep 29, 2025 · Updated Sep 29, 2025

Code injection in Knowage Server before 8.1.27 allows remote authenticated users to execute operating-system commands through MetaService. The checkRelationships path passes an attacker-controlled diff from value to a default JXPathContext, which resolves Java methods including Runtime.exec. A normal user with a valid session can create a model, submit the crafted relationship patch, and run commands with the server process's privileges.
