PolarVista xcode-mcp-server Suffers High-Severity OS Command Injection
The National Vulnerability Database has disclosed CVE-2026-7416, a high-severity OS command injection vulnerability in PolarVista xcode-mcp-server version 1.0.0. This flaw, rated 7.3 CVSS, resides in the build_project/run_tests function within the src/index.ts file’s MCP Interface component. Attackers can exploit this remotely by manipulating the Request argument.
This isn’t theoretical; an exploit for CVE-2026-7416 is publicly available. The project maintainers were reportedly notified early via an issue report but have not yet responded, leaving users exposed. The ability to inject OS commands remotely is a critical vector, allowing attackers to execute arbitrary code with the privileges of the affected server process.
For defenders, this means potential full system compromise. An attacker gaining remote command execution can establish persistence, exfiltrate data, or pivot further into the network. The public availability of an exploit significantly lowers the bar for adversaries, making exploitation highly probable for unpatched systems.
What This Means For You
- If your organization uses PolarVista xcode-mcp-server 1.0.0, you are directly exposed to remote OS command injection. Given the public exploit and lack of vendor response, assume this vulnerability is actively being scanned for and exploited. Isolate these systems immediately and assess for alternative solutions. A patch is critical, but until then, strict network segmentation and monitoring for anomalous activity originating from these servers are paramount.
