CVE-2025-57283 (opens in a new tab)How to fix?
Upgrade browserstack-local to version 1.5.9 or higher.
Overview
browserstack-local is a Nodejs bindings for BrowserStack Local
Affected versions of this package are vulnerable to Command Injection via the logfile variable in lib/Local.js. An attacker can execute arbitrary operating system commands by supplying crafted input to this variable. This is only exploitable if the attacker has the ability to set the logfile variable, which typically requires prior access to configuration files or the environment and permission to modify it.
Workaround
This vulnerability can be mitigated by implementing strict input validation of the logfile variable using an allow-list approach, permitting only alphanumeric characters, dots, dashes, underscores, and forward slashes, and rejecting any input containing other characters.
