Impact

The Wrangler command line tool (<[email protected] or <[email protected]) was affected by a directory traversal vulnerability when running a local development server for Pages (wrangler pages dev command). This vulnerability enabled an attacker in the same network as the victim to connect to the local development server and access the victim’s files present outside of the directory for the development server.
