CVE-2026-48723 Details
Description
The browserstack-cypress-cli is BrowserStack's CLI which allows users to run Cypress tests on BrowserStack. Versions prior to 1.36.4 are vulnerable to OS command injection via the cypress_config_file configuration parameter. In readCypressConfigUtil.js, the loadJsFile() function constructs a shell command by interpolating the user-controlled cypress_config_filepath value into a template literal, then executes it via child_process.execSync(). Shell metacharacters in the config path (specifically " and ;) allow breaking out of the quoted argument and injecting arbitrary commands. This issue has been fixed in version 1.36.6.
A command injection vulnerability has been identified in the BrowserStack Cypress CLI, specifically in versions prior to 1.36.4. The issue arises in the 'readCypressConfigUtil.js' file, where the 'loadJsFile()' function constructs a shell command by interpolating the user-controlled 'cypress_config_filepath' into a template literal. This command is then executed using 'child_process.execSync()'. The vulnerability allows shell metacharacters in the config path, particularly double quotes and semicolons, to break out of the quoted argument and inject arbitrary commands. This flaw could be exploited by creating a malicious 'browserstack.json' file that, when processed by the CLI, executes unintended commands on the user's machine.
Users can update to version 1.36.6 or later, where this vulnerability has been fixed.
