CVE-2026-79574Public exploitNetwork attack vector

Unauthenticated code execution via Nashorn condition evaluation

Published Sep 8, 2026 · Updated Sep 9, 2026

Code injection in the mpush 0.8.1 gateway server allows remote attackers to execute arbitrary OS commands through a crafted broadcast message. GatewayPushMessage.getCondition passes the attacker-controlled condition string to ScriptCondition, whose test method evaluates it with Nashorn without filtering. Exploitation requires TCP access to the unauthenticated gateway on port 3001, JDK 8, and at least one online user; commands run with the gateway JVM's privileges.
