Vite is a frontend tooling framework for javascript. Prior to versions 6.3.4, 6.2.7, 6.1.6, 5.4.19, and 4.5.14, the contents of files in the project root that are denied by a file matching pattern can be returned to the browser. Only apps explicitly exposing the Vite dev server to the network (using --host or server.host config option) are affected. Only files that are under project root and are denied by a file matching pattern can be bypassed. `server.fs.deny` can contain patterns matching against files (by default it includes .env, .env.*, *.{crt,pem} as such patterns). These patterns were able to bypass for files under `root` by using a combination of slash and dot (/.). This issue has been patched in versions 6.3.4, 6.2.7, 6.1.6, 5.4.19, and 4.5.14.
This vulnerability carries a MEDIUM severity rating with a CVSS v3.1 score of 5.3, indicating it can be exploited remotely over the network with relatively low complexity without requiring user interaction and does not require pre-existing privileges . The vulnerability impacts limited data confidentiality, for affected systems. Impacting 1 product from vitejs organizations running these solutions should prioritize assessment and patching.
Reported in 2025, this vulnerability emerged during an era marked by increased sophistication in supply chain attacks, cloud infrastructure vulnerabilities, and software-as-a-service (SaaS) security challenges. Security practices during this period emphasized zero-trust architectures, container security, and API protection.

SecUtils normalizes and enriches National Vulnerability Database (NVD) records by standardizing vendor and product identifiers, aggregating vulnerability metadata from both NVD and MITRE sources, and providing structured context for security teams. For vitejs's affected products, we extract Common Platform Enumeration (CPE) data, Common Weakness Enumeration (CWE) classifications, CVSS severity metrics, and reference data to enable rapid vulnerability prioritization and asset correlation. This record contains no exploit code, proof-of-concept instructions, or attack methodologies—only defensive intelligence necessary for patch management, risk assessment, and security operations.
