CVE-2026-118662
Vite: `server.fs.deny` bypassed with queries
Description
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.
