Exploit públicoNo conocidosin código público localizado

Se ha descubierto un fallo de seguridad en mcollina mcp-ripgrep hasta la versión 0.4.0. Afecta a una función no especificada del archivo src/index.ts del componente Advanced Search Tool. La manipulación del argumento fileType provoca una inyección de comandos del sistema operativo. El ataque requiere un enfoque local. El exploit se ha publicado y puede utilizarse en ataques. La existencia real de esta vulnerabilidad todavía se pone en duda en este momento.

Leer descripción completaMostrar menos

La propia función escapeShellArg del código, aplicada a los argumentos hermanos (omitida únicamente para fileType), indica que se trata de un descuido de CWE-78 y no de un diseño documentado. El responsable del proyecto cita la documentación: "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."
