Description

Vite provides frontend tooling. Prior to versions 2.9.16, 3.2.7, 4.0.5, 4.1.5, 4.2.3, and 4.3.9, Vite Server Options (`server.fs.deny`) can be bypassed using double forward-slash (//) allows any unauthenticated user to read file from the Vite root-path of the application including the default `fs.deny` settings (`['.env', '.env.*', '*.{crt,pem}']`). Only users explicitly exposing the Vite dev server to the network (using `--host` or `server.host` config option) are affected, and only files in the immediate Vite project root folder could be exposed. This issue is fixed in vite@4.3.9, vite@4.2.3, vite@4.1.5, vite@4.0.5, vite@3.2.7, and vite@2.9.16.

• CWE-50Path Equivalence: '//multiple/leading/slash'The product accepts path input in the form of multiple leading slash ('//multiple/leading/slash') without appropriate validation, which can lead to ambiguous path resolution and allow an attacker to traverse the file system to unintended locations or access arbitrary files.
• CWE-200Exposure of Sensitive Information to an Unauthorized ActorThe product exposes sensitive information to an actor that is not explicitly authorized to have access to that information.
• CWE-706Use of Incorrectly-Resolved Name or ReferenceThe product uses a name or reference to access a resource, but the name/reference resolves to a resource that is outside of the intended control sphere.
