## Description

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.
