Rsbuild before 2.0.9 contains a command injection vulnerability that allows attackers to execute arbitrary OS commands by supplying a crafted URL containing shell metacharacters to the server.open configuration on macOS. The openBrowser() function in packages/core/src/server/open.ts passes the URL through encodeURI() before interpolating it into a shell command executed via child_process.exec(), but because encodeURI() does not encode dollar signs, parentheses, or semicolons, embedded shell metacharacters are evaluated by /bin/sh, enabling arbitrary command execution.

Rsbuild versions before 2.0.9 contain a command injection flaw in the developer-server browser-launcher on macOS. The openBrowser() helper in packages/core/src/server/open.ts passes a URL through encodeURI() and then interpolates it into a string handed to child_process.exec(), and because encodeURI() leaves characters such as $, (, ), and ; untouched, a crafted URL is evaluated by /bin/sh and can execute arbitrary operating-system commands with the privileges of the developer running the dev server. …
