This vulnerability allows Vitejs to expose content of non-allowed files through specific query parameters, impacting only those applications that expose the Vite development server to the network. With a CVSS score of 5.3, organizations should evaluate their configurations, particularly if they have enabled the server host option. The urgency for defenders is high; organizations should address this in their priority patch cycle.
Risk to organizations includes unauthorized access to sensitive files, which could lead to data breaches or unauthorized information disclosure. The vulnerability was published on March 31, 2025, and has been confirmed to have exploitability, necessitating immediate attention.
Organizations that utilize Vitejs should immediately check their configurations against the fixed versions, which are 6.2.4, 6.1.3, 6.0.13, 5.4.16, and 4.5.11. Failure to patch could expose them to significant risks, especially if the server is publicly accessible.
For detailed insights on the vulnerability, organizations can refer to the penetration testing methodology and assess their exposure accordingly.
Vulnerability Details
Vite is a frontend tooling framework for JavaScript. The vulnerability is classified under CWE-200 (Information Exposure) and CWE-284 (Improper Access Control). This vulnerability is critical for those who have exposed the Vite dev server to the network, as it allows unauthorized access to sensitive files.
The CVSS score of 5.3 indicates a medium severity, with a high attack complexity due to the requirement for user interaction. The vulnerability specifically affects the Vite framework versions prior to the aforementioned patches.
Technical Analysis
The root cause of this vulnerability stems from the way Vite handles file access controls when using certain query parameters. When applications expose the Vite dev server to the network, they risk allowing unauthorized access to sensitive files via crafted requests.
This vulnerability can be exploited over the network, requiring no privileges and necessitating user interaction to trigger the exposure of sensitive content. As such, the confidentiality impact is high, while integrity and availability impacts remain unaffected.
Risk & Impact Analysis
Real-world deployment risks associated with this vulnerability can lead to significant data breaches, especially if the application is publicly accessible. The blast radius potential is considerable for organizations using Vitejs without proper configurations, as sensitive files may be exposed.
Given the CVSS score and its classification in the KEV catalog, organizations should prioritize this vulnerability within their patch management processes.
