Description
@vitejs/plugin-rs provides React Server Components (RSC) support for Vite. Versions 0.5.5 and below are vulnerable to arbitrary remote code execution on the development server through unsafe dynamic imports in server function APIs (loadServerAction, decodeReply, decodeAction) when integrated into RSC applications that expose server function endpoints. Attackers with network access to the development server can read/modify files, exfiltrate sensitive data (source code, environment variables, credentials), or pivot to other internal services. While this affects development servers only, the risk increases when using vite --host to expose the server on all network interfaces. This issue is fixed in version 0.5.6.

Compliance Impact

This vulnerability allows attackers to exfiltrate sensitive data such as source code, environment variables, and credentials from development servers. Such data breaches could lead to non-compliance with standards and regulations like GDPR and HIPAA, which require protection of sensitive information and personal data. Therefore, exploitation of this vulnerability may result in violations of these compliance requirements, especially if sensitive or personal data is exposed or compromised.

Executive Summary

@vitejs/plugin-rs versions 0.5.5 and below have a vulnerability that allows arbitrary remote code execution on the development server. This happens through unsafe dynamic imports in server function APIs when used in React Server Components applications that expose server function endpoints. Attackers with network access to the development server can exploit this to execute code remotely.

Impact Analysis

An attacker with network access to the development server can read or modify files, exfiltrate sensitive data such as source code, environment variables, and credentials, or use the compromised server to pivot to other internal services. The risk is higher if the development server is exposed on all network interfaces using vite --host.

Mitigation Strategies

Upgrade @vitejs/plugin-rs to version 0.5.6 or later, as this version fixes the vulnerability. Additionally, avoid exposing the development server on all network interfaces using the vite --host option to reduce risk.
