In JetBrains IntelliJ IDEA before 2026.2.2 missing TLS and authentication on the IJent gRPC server allowed local code execution on Remote Development hosts
AnalysisAI
Local code execution on Remote Development hosts is possible in JetBrains IntelliJ IDEA versions before 2026.2.2 due to the IJent gRPC server running without TLS encryption or any authentication mechanism. The IJent agent, deployed on remote hosts when the Remote Development feature is in use, accepts connections from any local process without requiring credentials, enabling arbitrary command execution under the agent's security context. …
