CVE-2025-24010 in vite
Summary
by MITRE • 01/20/2025
Vite is a frontend tooling framework for javascript. Vite allowed any websites to send any requests to the development server and read the response due to default CORS settings and lack of validation on the Origin header for WebSocket connections. This vulnerability is fixed in 6.0.9, 5.4.12, and 4.5.6.

The vulnerability identified as CVE-2025-24010 affects Vite, a popular frontend tooling framework for JavaScript development. This security flaw stems from inadequate cross-origin resource sharing (CORS) configuration within Vite's development server implementation. The issue specifically manifests in the default settings that fail to properly validate WebSocket connections, creating a significant attack surface for malicious actors who can exploit this weakness to perform unauthorized operations against the development environment.
The technical flaw lies in the absence of proper origin validation mechanisms for WebSocket connections within Vite's development server. When developers run Vite in development mode, the server listens on localhost ports and typically accepts connections from any origin without adequate verification. This configuration allows external websites to establish WebSocket connections to the development server and subsequently send arbitrary requests to internal services. The vulnerability is particularly concerning because it bypasses standard CORS protections that normally restrict cross-origin requests, enabling attackers to exploit the development server as an entry point for further reconnaissance or exploitation activities.
The operational impact of this vulnerability extends beyond simple data exposure, as it provides attackers with the capability to interact with the development server's internal components and potentially access sensitive information. Since Vite development servers often run with elevated privileges or access to local file systems, an attacker could leverage this vulnerability to read files, execute commands, or gain insights into the application's internal structure. The default configuration means that any developer who runs Vite without modifying security settings is potentially exposed to this attack vector, making it a widespread concern across development environments.
The vulnerability has been addressed through updates to Vite's core framework, with fixes released in versions 6.0.9, 5.4.12, and 4.5.6. These releases implement proper origin validation for WebSocket connections and enhance CORS configuration to prevent unauthorized access. Organizations should immediately upgrade to these patched versions to mitigate the risk of exploitation. The fix aligns with security best practices outlined in CWE-346, which addresses "Origin Validation Error" and emphasizes the importance of validating the origin of requests to prevent cross-origin attacks. Additionally, this vulnerability relates to techniques described in the MITRE ATT&CK framework under the T1190 category, which covers "Exploit Public-Facing Application" and highlights the importance of securing development environments that may be exposed to external networks.
