CVE-2025-57283 identifies a command injection vulnerability in the Node.js package browserstack-local version 1.5.8. The vulnerability stems from improper sanitization of the 'logfile' variable within the lib/Local.js source file. Command injection (CWE-94) allows an attacker to inject and execute arbitrary commands on the host system. The CVSS 3.1 vector (AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H) indicates that the attack requires local access with low complexity and privileges but no user interaction, and it can compromise confidentiality, integrity, and availability fully. The vulnerability could be exploited by an attacker who has some level of access to the system where browserstack-local is installed, potentially leading to full system compromise. Browserstack-local is commonly used to establish secure tunnels for testing web applications locally, meaning development and testing environments are primarily affected. No patches are currently linked, and no known exploits have been reported in the wild, but the high severity score suggests that exploitation could have serious consequences. The vulnerability was reserved in August 2025 and published in January 2026, indicating recent discovery. The lack of patch links suggests that remediation may still be pending or in progress. This vulnerability highlights the importance of input validation and sanitization in software components that handle user-controlled variables.

For European organizations, the impact of CVE-2025-57283 can be significant, especially for those relying on browserstack-local in their development and testing pipelines. Successful exploitation could lead to unauthorized command execution, resulting in data breaches, system manipulation, or service disruption. Confidentiality is at risk as attackers could access sensitive data; integrity could be compromised by altering files or configurations; availability could be affected by system crashes or denial of service. Organizations in sectors such as software development, financial services, and critical infrastructure that use Node.js-based tools may face increased risk. The vulnerability could also be leveraged as a foothold for lateral movement within internal networks. Given the local attack vector, insider threats or attackers who have gained initial access could exploit this vulnerability to escalate privileges or maintain persistence. The absence of known exploits in the wild currently reduces immediate risk but does not eliminate the threat, especially as public disclosure may prompt attackers to develop exploits.

To mitigate CVE-2025-57283, organizations should first monitor for official patches or updates from the browserstack-local maintainers and apply them promptly once available. In the interim, restrict usage of browserstack-local to trusted environments and limit access to systems where it is installed to authorized personnel only. Implement strict input validation and sanitization for any variables passed to browserstack-local, especially the 'logfile' parameter, to prevent injection of malicious commands. Employ application whitelisting and endpoint protection solutions to detect and block suspicious command execution. Conduct regular audits of development and testing environments to identify unauthorized changes or anomalous behavior. Consider isolating development tools in sandboxed or containerized environments to limit potential damage from exploitation. Educate developers and system administrators about the risks associated with command injection vulnerabilities and encourage secure coding practices. Finally, maintain robust logging and monitoring to detect any attempts to exploit this vulnerability.
