Official Description

Tina is a headless content management system. Prior to 2.1.8, the TinaCMS CLI dev server configures Vite with server.fs.strict: false, which disables Vite's built-in filesystem access restriction. This allows any unauthenticated attacker who can reach the dev server to read arbitrary files on the host system. This vulnerability is fixed in 2.1.8.
