mcollina mcp-ripgrep up to 0.4.0 Advanced Search Tool src/index.ts fileType os command injection ⚔ [Disputed]

Summaryinfo

A vulnerability was found in mcollina mcp-ripgrep up to 0.4.0. It has been rated as problematic. Affected by this vulnerability is an unknown functionality of the file src/index.ts of the component Advanced Search Tool. This manipulation of the argument fileType causes os command injection. This vulnerability appears as CVE-2026-113378. The attack requires local access. In addition, an exploit is available. It is still unclear if this vulnerability genuinely exists. The code's own escapeShellArg on sibling arguments (skipped only for fileType) indicates that this is a CWE-78 oversight, not a documented design. The project maintainer cites the documentation: "This MCP server executes shell commands using the ripgrep tool. While efforts have been made to safely escape arguments, use caution when providing input, as it runs commands on your machine."
