Vite's server.fs.deny bypassed with /. for files under project root
Summary
The contents of files in the project root that are denied by a file matching pattern can be returned to the browser.
Impact
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.
- Examples of file matching patterns:
.env,.env.*,*.{crt,pem},**/.env - Examples of other patterns:
**/.git/**,.git/**,.git/**/*
Details
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 (/.).
