CVE-2026-119198: Nuxt dev server arbitrary file read through client error reports
A client that can connect to the dev server’s HMR socket can send a nuxt:dev:client-error event whose message ends in an absolute file path. The dev server reads that file while building the error report, and its contents are returned in the error overlay, on the dev error channel, and in the report shown in the terminal.
