Elevated risk52th percentile - higher than 52% of all known CVEs
Summary
Neo.mjs contains a command injection vulnerability within the FileSystemService.mjs component of the ai/mcp/server/file-system MCP server, where the checkSyntax() and runPlaywrightTest() functions unsafely interpolate caller-controlled absolutePath values into shell commands, enabling arbitrary OS command execution when an AI agent is induced to invoke these tools. Commit 88c77fc fixes these vulnerabilities.
Risk Assessment
The risk is the ability to execute arbitrary OS commands via an AI agent, potentially leading to full system compromise if the agent is manipulated.
Recommendation
Upgrade Neo.mjs to a version containing commit 88c77fc or apply the appropriate patch immediately.
