Attack profile from CVSS 4.0 · CNA. Fix status from CNA and GitHub. Impact type from CWE-284.

Summary

Vite from 6.4.4 before 6.4.5 evaluates server.fs.deny before stripping loader query parameters such as ?raw, so the deny check can be bypassed. When the development server is exposed to the network and a sensitive file is inside server.fs.allow but matched by server.fs.deny, an unauthenticated remote attacker can append one of these query parameters to retrieve the denied file. The flaw is a validate-before-canonicalize ordering error (CWE-180) that results in improper access control (CWE-284).

Description from the CNA

Vite is a frontend tooling framework for JavaScript. From 6.4.4 until 6.4.5, the Vite development server can evaluate server.fs.deny before stripping loader query parameters such as ?raw, ?import&raw, or ?import&url&inline. When the development server is exposed to the network and a sensitive file is inside server.fs.allow but matched by server.fs.deny, an unauthenticated attacker can append one of these queries and retrieve the denied file. This issue is fixed in version 6.4.5.
