CVE-2026-49988
Full vulnerability record from the local CVENow database.
Description
Repomix is a tool that packs repositories into AI-friendly files. Prior to 1.14.1, the Repomix MCP server attach_packed_output and read_repomix_output flow can register and read arbitrary local .json, .txt, .md, or .xml files without the file_system_read_file runSecretLint() safety check or Repomix packed-output validation, allowing MCP callers to bypass the local file-read secret-scanning boundary. This issue is fixed in version 1.14.1.

Antes de la versión 1.14.1, el flujo attach_packed_output y read_repomix_output del servidor MCP de Repomix puede registrar y leer archivos locales arbitrarios .json, .txt, .md o .xml sin la comprobación de seguridad file_system_read_file runSecretLint() o la validación de salida empaquetada de Repomix, lo que permite a los llamadores de MCP eludir el límite de escaneo de secretos de lectura de archivos locales. Este problema está solucionado en la versión 1.14.1."
