CVE-2026-7416
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedA vulnerability was found in PolarVista xcode-mcp-server 1.0.0. This issue affects the function build_project/run_tests of the file src/index.ts of the component MCP Interface. The manipulation of the argument Request results in os command injection. The attack may be launched remotely. The exploit has been made public and could be used. The project was informed of the problem early through an issue report but has not responded yet.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceOS command injection vulnerability in the PolarVista xcode-mcp-server MCP Interface (src/index.ts). The build_project/run_tests function processes a Request argument without proper sanitization, allowing attackers to inject arbitrary OS commands via the manipulated input.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Locate the xcode-mcp-server installationSearch for the xcode-mcp-server package in your node_modules, project dependencies, or installed binaries. Common paths include node_modules/xcode-mcp-server or global npm installation directories.Affected if The package is present in your environment
-
Identify the installed versionRun 'npm list xcode-mcp-server' or check package.json for the version field. Compare this to any official release notes or version tags from PolarVista.Affected if You cannot confirm the version is beyond the patched release (if known)
-
Inspect the vulnerable source fileLocate src/index.ts within the xcode-mcp-server package directory. Search for the 'build_project' and 'run_tests' functions and examine how they handle Request arguments.Affected if The file exists and contains these functions with unsanitized Request parameter handling
-
Verify the MCP interface is enabledCheck your server configuration or startup files for MCP server activation. Look for references to xcode-mcp-server in your server startup scripts, config files, or service definitions.Affected if The MCP interface is running or configured to run
-
Check for external or untrusted input exposureReview how the build_project/run_tests functions are invoked. Determine if the Request input can originate from external sources, network requests, or user-controlled data rather than only trusted internal calls.Affected if The vulnerable functions process input from external or untrusted sources
You are likely affected if the xcode-mcp-server is installed with its src/index.ts containing unsanitized Request handling in build_project/run_tests and external input can reach these functions through the MCP interface.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataImplement strict input validation and sanitization on all Request arguments before use in command execution. Replace dynamic command construction with parameterized APIs or safe command execution methods that avoid shell interpretation of user input.
