CVE-2026-54785

gemini-bridge is a lightweight MCP server bridging AI agents to Google's Gemini AI via the official CLI. From 1.0.0 until 1.3.1, consult_gemini_with_files in inline mode read any file path supplied in the files argument without confining it to the working directory, then forwarded the contents to the Gemini CLI. Because the caller also controls query, the file contents are echoed back through the Gemini round-trip (and sent to Google), making this an arbitrary local file read. This issue is fixed in version 1.3.1.

Summary		(es) gemini-bridge es un ligero servidor MCP que conecta agentes de IA con la IA Gemini de Google a través de la CLI oficial. Desde la versión 1.0.0 hasta la 1.3.1, consult_gemini_with_files en modo en línea leía cualquier ruta de archivo proporcionada en el argumento files sin confinarla al directorio de trabajo, luego reenviaba el contenido a la CLI de Gemini. Debido a que el llamador también controla la consulta, el contenido del archivo es devuelto a través del viaje de ida y vuelta de Gemini (y enviado a Google), lo que convierte esto en una lectura arbitraria de archivos locales. Este problema está solucionado en la versión 1.3.1.
