CVE-2025-30208:
JavaScript vulnerability analysis and mitigation

Overview

Vite, a provider of frontend development tooling, disclosed a vulnerability (CVE-2025-30208) affecting versions prior to 6.2.3, 6.1.2, 6.0.12, 5.4.15, and 4.5.10. The vulnerability was discovered on March 24, 2025, and allows attackers to bypass file system restrictions in the Vite development server. The vulnerability affects applications that explicitly expose the Vite dev server to the network using the --host or server.host configuration option (NVD, GitHub Advisory).

Technical details

The vulnerability exists in Vite's @fs functionality which normally denies access to files outside of the Vite serving allow list. By adding ?raw?? or ?import&raw?? to the URL, attackers can bypass this limitation. The bypass occurs because trailing separators such as ? are removed in several places but are not properly accounted for in query string regular expressions. The vulnerability has been assigned a CVSS v3.1 base score of 5.3 (Medium) with the vector string CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:N/A:N (NVD, Security Online).

Impact

When exploited, this vulnerability allows attackers to access and return the contents of arbitrary files to the browser that should be restricted. This poses a significant security risk for applications that expose their Vite development server to the network, as sensitive information could be exposed to unauthorized users (GitHub Advisory, Security Online).

Mitigation and workarounds

The vulnerability has been patched in Vite versions 6.2.3, 6.1.2, 6.0.12, 5.4.15, and 4.5.10. Users are strongly advised to upgrade to these patched versions. As a general security practice, it is recommended to avoid exposing development servers to the network whenever possible (NVD, GitHub Advisory).

Community reactions

The security community has responded with concern to this vulnerability, particularly given the widespread use of Vite in modern web development. The issue has gained significant attention due to the release of a proof-of-concept exploit and the potential impact on exposed development servers (Security Online).
