Users should upgrade rsbuild to version 2.0.9 or later, where this vulnerability is fixed. No other mitigation or temporary workaround is indicated. Patch status is confirmed by the version boundary (fixed in 2.0.9).
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.
