What is CVE-2026-48723?

The browserstack-cypress-cli, utilized for executing Cypress tests on BrowserStack, is vulnerable to OS command injection in versions prior to 1.36.4. This vulnerability arises from improper handling of the cypress_config_file parameter, where user-controlled input is used to construct shell commands. Specifically, malicious shell metacharacters in the configuration path can escape quoted arguments, allowing attackers to inject arbitrary commands. This critical issue has been addressed in version 1.36.6, emphasizing the importance of always using the latest versions to ensure security.
