CVE-2026-10144

Command execution via shell-interpreted browser URL

Published Sep 15, 2026 · Updated Sep 15, 2026

Command injection in Web Infra Rsbuild before 2.0.9 allows attackers to execute arbitrary OS commands through a crafted server.open URL. The openBrowser() function applies encodeURI() and interpolates the result into a child_process.exec() shell command, leaving $, parentheses, and semicolons active. Exploitation requires control of the server.open URL on macOS, where /bin/sh evaluates the embedded shell syntax with the Rsbuild process's privileges.
